Entanglement is one of the most valuable resources in the quantum realm and is, for example, the driving force behind quantum cryptography. Theoretically, it may be possible to extract an infinite number of quantum entanglements from the universe.
Normally, when interacting with a quantum field, its state changes; henrik wilming At Hannover Leibniz University in Germany, we were looking for a case where this could be avoided. This gave him the idea of “quantum…''.
