Simulating magnetization in a Heisenberg quantum spin chain

The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at Google Quantum AI and their ...

100 kilometers of quantum-encrypted transfer

Researchers at DTU have successfully distributed a quantum-secure key using a method called continuous variable quantum key distribution (CV QKD). The researchers have managed to make the method work over a record 100 km ...
