Artist Representation of Qubits in the Quantum Twins Simulator
Silicon Quantum Computing
A groundbreaking large-scale quantum simulator has the potential to unveil the mechanisms of exotic quantum materials and pave the way for their optimization in future applications.
Quantum computers are set to leverage unique quantum phenomena to perform calculations that are currently unmanageable for even the most advanced classical computers. Similarly, quantum simulators can aid researchers in accurately modeling materials and molecules that remain poorly understood.
This holds particularly true for superconductors, which conduct electricity with remarkable efficiency. The efficiency of superconductors arises from quantum effects, making it feasible to implement their properties directly in quantum simulators, unlike classical devices that necessitate extensive mathematical transformations.
Michelle Simmons and her team at Australia’s Silicon Quantum Computing have successfully developed the largest quantum simulator to date, known as Quantum Twin. “The scale and precision we’ve achieved with these simulators empower us to address intriguing challenges,” Simmons states. “We are pioneering new materials by crafting them atom by atom.”
The researchers designed multiple simulators by embedding phosphorus atoms into silicon chips. Each atom acts as a quantum bit (qubit), the fundamental component of quantum computers and simulators. The team meticulously configured the qubits into grids that replicate the atomic arrangement found in real materials. Each iteration of the Quantum Twin consisted of a square grid containing 15,000 qubits, surpassing any previous quantum simulator in scale. While similar configurations have been built using thousands of cryogenic atoms in the past, Quantum Twin breaks new ground.
By integrating electronic components into each chip via a precise patterning process, the researchers managed to control the electron properties within the chips. This emulates the electron behavior within simulated materials, crucial for understanding electrical flow. Researchers can manipulate the ease of adding an electron at specific grid points or the “hop” between two points.
Simmons noted that while conventional computers struggle with large two-dimensional simulations and complex electron property combinations, the Quantum Twin simulator shows significant potential for these scenarios. The team tested the chip by simulating the transition between conductive and insulating states—a critical mathematical model explaining how impurities in materials influence electrical conductivity. Additionally, they recorded the material’s “Hall coefficient” across different temperatures to assess its behavior in magnetic fields.
With its impressive size and variable control, the Quantum Twins simulator is poised to tackle unconventional superconductors. While conventional superconductors function well at low temperatures or under extreme pressure, some can operate under milder conditions. Achieving a deeper understanding of superconductors at ambient temperature and pressure is essential—knowledge that quantum simulators are expected to furnish in the future.
Moreover, Quantum Twins can also facilitate the investigation of interfaces between various metals and polyacetylene-like molecules, holding promise for advancements in drug development and artificial photosynthesis technologies, Simmons highlights.
Does the world truly require another PowerWash Simulator game? Many would argue against it, likely those who haven’t experienced the original and fail to grasp its charm, but who prefer to tilt their heads in confusion and disapproval and ask: “What do you do in the game? Just wash things?”
(It’s rather unfair that other hobbies don’t face this scrutiny. No one questions, “Wait, you’re just running in circles at a 5k?” or “So, you’re just playing with a ball?”)
The quick answer is yes. Simply direct the hose at the grime around you, be it a bungalow, a monster truck, or Lara Croft’s mansion, and obliterate it. After finishing each section, a calming “ding” sounds, and your brain gets a dopamine boost. This is the sole sound in the game apart from the rush of water and the sporadic clatter of metal ladders. The entire experience is wonderfully pleasant, deeply fulfilling, and captivating. I absolutely love it.
I was so enamored that in 2023, I streamed PowerWash Simulator on Twitch for 24 hours, 6 minutes, and 33 seconds – setting a Guinness World Record for the longest gaming marathon.

Not recommended. While the game is enjoyable, the novelty tends to wear off after around 20 hours. I recall things getting strange around 4 AM. The vibrant colors of the children’s play area I was cleaning began swirling in a psychedelic whirlwind. My vision blurred, my fingers ached, and I felt a surge of frustration towards the local council for the state of the climbing frame.
I persevered, buoyed by the Twitch community’s support. They reminded me of the reality outside the game. Yet, I had lingering flashbacks for months. Occasionally, as I lay in bed at night, I’d think I could still hear the constant hissing of the jets, worried I might have a ringing in my ears. I still struggle to walk past a slide without checking for mold underneath.
Interestingly, after my record-setting marathon, I didn’t feel inclined to return to PowerWash Simulator for a while. However, diving into the sequel brought back that thrill of achievement that comes from erasing the final speck of grime from a chrome toilet bowl. Pure bliss.
This article helps you to be more forgiving about cleaning every nook and cranny. There’s also a new target icon that indicates missed spots, making mission completion less frustrating.
And of course, there are fresh objects to clean. PowerWash Simulator 2 offers a total of 38 missions, featuring airships, mobility scooters, shopping malls, and more. New tools include a surface cleaner for efficient floor scrubbing and a harness system for rappelling down buildings. Additionally, there’s a new home base to showcase your achievements. This is particularly appealing if you’re the type to display (three) Guinness World Record certificates prominently for delivery drivers to see upon entry.
While none of these enhancements create a substantial shift from the original game, it’s also unlikely that a sequel will attract those who didn’t understand the initial charm. Nevertheless, PowerWash Simulator 2 delivers what fans desire: fresh cleaning challenges, new toys to experiment with, and even less difficult but gratifying gameplay. Plus, there’s the option to occasionally draw crude representations of male genitalia in the grime for comedic effect. In a world filled with chaos, this is exactly the game we need right now.
With the rise of retail simulators, the gaming landscape has become quite dense. On the Comet Trail in Stardew Valley, this genre flourishes, featuring protagonists who revive their lives and careers in a semi-rural setting filled with pastoral charm, often taking on blue-collar jobs. Players engage with the locals, influence their lives, and resolve community issues—perhaps even uncovering a mystery or two. They might even find love along the way. Essentially, these characters are pixelated heirs to the legacy of Harvest Moon, yet recent titles from Crinkle Cut Games offer a slightly different take on the cozy shop simulation experience.
In Dissevery, you find yourself taken under the wing of your cunning aunt and joining the franchise’s supermarket brunch initiative. The game’s unique twist focuses on building up local supermarkets rather than community centers, given the quaint absence of roadways in Stardew Valley. Dissiventy weaves a narrative focused on revitalizing the economy of a small town, balancing sharp challenges within a cozy game framework.

The aspect of building a supermarket is indeed satisfying. Stock your store, open its doors, and let the customers in. The till system initially functions like a tricky little math puzzle, but it evolves into something more intricate as you progress. Speed becomes crucial—you’ll need to keep customers satisfied, ensure shelves are stocked, floors are tidy, and everything runs efficiently. After a busy day, the store closes, allowing you to breathe, clean up, and retreat to a cozy trailer outside your aunt’s grand home. Aunt Terror is a savvy businesswoman with grand ambitions, and you’ll need to navigate her disputes with the locals, some of whom she dismisses to let you take charge. This unique tone is quite refreshing; it strays from the typical cute aesthetic, focusing instead on supermarket management rather than a whimsical farm life.
The graphics can be somewhat misleading. While the pixel art may initially suggest a sweet and innocent vibe, the town you inhabit is far from pristine. There are dilapidated docks, shuttered shop fronts, and peeling posters on the walls, hinting at a deeper narrative. Even the music complements this atmosphere, providing ambient yet engaging background sounds that enhance the overall experience.
Consulting with locals involves addressing their concerns, often requiring some tact due to your aunt’s tricky nature. This task carries significant responsibility and demands intense focus. At times, the controls can feel a bit awkward. I found the touchscreen options on the Steam Deck somewhat challenging to navigate, particularly in the early game stages where there aren’t many options and you’re juggling basic tasks. However, the initial resistance isn’t overwhelming. I was impressed by how the challenges gradually become more manageable, emphasizing the rewarding nature of everyday tasks.
Dissiventy serves as a noteworthy addition to the cozy life simulation genre, presenting a hands-on experience filled with ambition. It deviates from typical tropes while maintaining an engaging focus. While romance may not be a primary theme in managing a supermarket, there’s plenty to accomplish, ensuring it still offers an enjoyable gaming experience.
I spent 85 hours immersed in Death Stranding 2 before it hit me: what I was experiencing was an apocalyptic nightmare unfolding on an Earth plagued by a Death Monster. Yet, I found myself treating it as a delightful game. For countless hours, I navigated a photorealistic landscape in a pickup truck, delivering packages to remote communities and constructing new roads. My motivation to complete the main storyline was purely to unlock additional map regions, allowing me to connect with new characters and expand my road network. It felt blissful and entertaining.
I’m far from the only one indulging in games like this. The “Cozy Games” niche has flourished into a vibrant cottage industry over the past five years, featuring countless indie titles that captivate a passionate community. Successful crossovers like Minecraft, Stardew Valley, and Untitled Goose Game have set the bar high. This month, Steam offers a variety of charming titles including Cat’s Post Office, delightful food truck management sims, and cozy games centered around quaint bookstores. These games typically share common traits: small, often youthful development teams working remotely, brief gameplay sessions, low-stakes challenges, and stylistic visuals that serve both aesthetic and economic purposes.
Yet, it’s curious that we don’t see more luxurious mainstream, Triple A titles despite a clearly established audience for cozy gaming. Major producers like Ubisoft, EA, and Xbox struggle to innovate, opting instead to churn out the next cookie-cutter live service shooter to compete with Fortnite, often wasting millions in the process. I wonder why no one has attempted a grand open-world adventure geared toward positive interactions and gentle drama. The realms of television, film, and literature are brimming with this type of content. Where’s my video game rendition of *Call the Midwife*? Why can’t I ride a bicycle through a 1950s setting? What would be the gaming equivalent of *Downton Abbey* or *Gilmore Girls*?

I recognize the most apparent reason behind this trend. Like Hollywood, mainstream game development focuses heavily on minimizing risk, leading to an industry saturated with action, violence, and power fantasy. However, cultural discussions reveal that cozy gamers appreciate narrative and mechanics over visual fidelity. Moo Yu, Creative Director at Small Studio, mentions, “I think a cozy game of higher budget will certainly be developed. This audience values a broader spectrum of experiences across various price ranges.”
And this is a key point. High-end graphics and expansive worlds aren’t the only worthwhile goals; they represent but one form of immersive experience. Untitled Goose Game wouldn’t hold the same charm if it featured a hyper-realistic environment with a goose rendered in 100,000 texture-mapped polygons. The beauty of *Stardew Valley* lies in its vibrant retro aesthetic. The art’s appeal is not merely in high production value; it’s also about the comfort derived from limitation in both choice and outcomes. The game gently guides you, saying, “Everything will be alright.”

My friend John Cartwright, an experienced game developer who mentors small studios in Australia and New Zealand, shared his thoughts when I reached out. “The cozy game’s market is limited in size, a domain often dominated by small indie teams with constrained budgets. All cozy games share a safe environment with low-stakes gameplay, which has largely remained underdeveloped, especially during the stress of Covid. The simplistic visuals were an added source of comfort and attraction.”
Creating charm is no simple feat. It can’t be manufactured with a new, expensive graphics engine or by having 500 employees working overtime. Just like you can’t establish a high-tech charm center in a desert. In larger productions, charm emerges organically, akin to monumental TV dramas, yet it’s finite and precarious. The entire notion of a cozy game as a defined genre or intentional gameplay element is still relatively nascent. Historically, games have been focused on winning, while elements emphasizing kindness and empathy have yet to be officially recognized. There’s a clever saying that contrasts games and movies: explosions are cheap, yet capturing human emotion through close-ups is a costly endeavor. Given the interactive medium’s historically limited visual naturalism, portraying drama through a date invitation can be more challenging than simply depicting conflict. But we have a century’s worth of animation to showcase how charm, comfort, and emotional closeness can be represented through the most iconic and stylized palettes.
Moo Yu remains optimistic that a cozy, epic, mainstream title will make its way into gaming’s future. He cites the fashion-centric role-playing game Infinity Nikki as an example. Until that time, I’ll continue to feign interest in the issues surrounding chiral contamination and extinction, all for the chance to save the kangaroos, meet the inventors, and traverse the stunning yet irradiated landscapes in my trusty truck. Sometimes you have to play their game to win for yourself.
What to Play
Retro Shooter…Operation Night Striker. Photo: Taito/M2
August has proven to be a fantastic month for retro arcade collections, and we can’t resist recommending one more before we venture back to contemporary titles. Operation Night Striker is a collection of four iconic Taito shooters, effectively blending action film tropes with gaming elements, including the innovative light gun classic, Operation Wolf. It also features its sequel, Thunderbolt operations, as well as two lesser-known gems: the Cyberpunk Flying Car shooter Night Striker and Space Gun, which takes a whimsical approach with its face-hugger and flamethrower. As is usually the case with these collections, new features have been integrated, and gamers playing the Switch version can utilize Joycon as a makeshift light gun. While it may not be highly accurate, it recalls the nostalgia of using the original maggot gun controller from Operation.
These vibrant, fast-paced, and delightfully absurd popcorn games perfectly capture the essence of their era, complete with smooth-scrolling 2D backgrounds, electrifying soundtracks, engaging gameplay loops, and brawny heroes. You’ll be hooked!
Available on: PC, Switch Estimated playtime: Over 10 hours

In a tale that echoes the antics of Verca Salt, McDonald’s Japan had to cancel a Pokémon promotion due to massive food waste and rampant scalping. According to Eurogamer, an exclusive Pikachu card was offered as part of a limited edition Happy Meal deal, leading fans to queue for hours, resulting in fights and food waste in the streets as scalpers took advantage, listing the cards at inflated prices on auction sites.
It’s always enlightening to read Rob Fahey’s Industry Analysis on GamesIndustry.biz. This week, he discusses the fate of PlayStation, scrutinizing how consoles remain profitable despite pitfalls, including the seemingly obligatory shift to live services that have failed to yield meaningful returns.
Looking into the future, Xbox has changed the game design landscape over the last 20 years. In an interesting analysis at AV Club, they explore how gamers have responded to the commercialization of gaming and its impact on design.

Rich John from Bluesky raised an interesting point:
“Is it beneficial for the industry that a behemoth like GTA VI garners so much media attention and expected revenue? How will this impact other publishers?”
To put it simply, there’s no major gaming company with high hopes for 2026, which will coincide with Rockstar’s highly anticipated release window. As illustrated in a recent industry newsletter, three major Triple A developers have adjusted their timelines, giving it a wide berth, significantly impacting development teams who might have invested years planning for that release slot. This situation can create media and marketing black holes.
However, this isn’t all negative. When GTA V debuted in 2013, it didn’t obliterate every game in its path, as seen with casual mobile games like Puzzle & Dragon and Candy Crush, both of which thrived alongside titles that garnered dedicated fanbases like World of Warcraft and Call of Duty. Furthermore, monumental successes like GTA V often spark widespread attention, interest, and potential investments across the entire industry, leading to follow-up titles. Moreover, these giants often introduce innovative design elements to the market, as GTA Online was the pioneering live service experiment.
In essence, it’s beneficial; ripe with potential. While the immediate fallout could be challenging for other studios, as evidenced by GTA V, casual gamers and ardent followers of other franchises are unlikely to abandon their favorites for the latest Rockstar title. Additionally, the ripple effect of a blockbuster’s success opens avenues for future projects. Much like Hollywood post-*Star Wars*, where studios dared to venture into big-budget sci-fi genres, we could see more opportunities presented in the aftermath of such monumental success, even if it’s achieved by competitors.

When I began my career in gaming journalism three decades ago, I missed the chance to review my favorite console, the Sega Mega Drive. While a few titles were still being launched in 1995, Games Magazine World dominated the headlines, and everyone was eager to hear about the Sony PlayStation and Sega Saturn. It felt like a painful setback.
Fast forward to 2025, where there’s a renewed enthusiasm for creating new games for classic home computers and consoles, highlighted by Agricultural Simulator: 16-bit Edition, which is part of the Agricultural SIM series for Mega Drive. This passion project, developed by Renzo Thönen, the lead-level designer and co-owner of Agricultural Simulation Studio Giants Software, was made using the open-source Mega Drive Development Kit and produced in a limited run of authentic Mega Drive cartridges. When I inserted this new title into my father’s old Mega Drive II console, a wave of nostalgia hit me. Yet, I soon realized I had underestimated it.
Agricultural Simulator: 16-bit Edition features a steady cycle of sowing, harvesting, and selling within an isometric environment, populated with essential buildings like fuel depots, seed stores, and garages. You start with a basic tractor and harvester, but by diligently farming the land, you can upgrade your equipment and acquire more powerful vehicles as you cultivate and market wheat. Eventually, you’ll generate enough revenue to unlock a new farming area, although the core gameplay remains unchanged. As the seasons progress, you slowly navigate the tractor over the fields, sowing and harvesting meticulously.
In this simplified format, the farming simulator’s tranquil pace may seem tedious and repetitive. All that’s required is to efficiently manage tasks, with complex, detailed 3D graphics, real-time weather systems, and extra activities stripped away. Again and again. Let’s be real: modern, intricate 3D simulations were being designed for consoles released concurrently with the advent of the World Wide Web, and the initial mass-produced Nokia phone still poses a technical challenge.

Yet somehow, the system still resonates. Perhaps it’s the charming chug of the tractor’s sound effect, or the slightly erratic steering that frequently leads to crashes into trees. Or maybe it’s just the pure nostalgia evoked by rugged 2D graphics. I can’t quite place it. I found myself engrossed in play. Longtime Mega Drive users might reminisce about the thrill of games set in deserts, jungles, or city environments, or the chaotic isometric strategies that defined the era. But can you imagine experiencing today’s genres on this vintage hardware, and how might they score in contemporary gaming publications like Sega Power or Mega?
Perhaps there are other Mega Drive enthusiasts out there who share a thrill for reinventing something familiar, akin to watching 4K Blu-ray movies on a Toshiba VCR. With only 1,000 units produced, safeguarding this gem may prove challenging. However, Giants Software has previously launched a Commodore 64 version of the game, Farming Simulator C64, which is now accessible on PC. Maybe this emulated edition will find a way onto modern platforms.
Nevertheless, akin to a deluxe remaster of a cherished vinyl record, the format itself carries emotional significance. This is why Giants Software isn’t the only one reviving classic cartridges for retro consoles. The fantastic puzzle platformer Tanglewood made its debut on the Mega Drive a few years back, and Limited Run Games continues to produce an extensive array of new SNES cartridges for classic titles.
I often imagine my father reviewing this recent release of the last console we enjoyed together. Given his fond memories of summer farming, I’m certain he would have relished this game. For now, I’m content to cultivate these fields, sell a bounty of wheat, and appreciate the serene cycle of nature, depicted through this outdated yet endearingly charming medium.
