Quantum physicists have found a way to make clouds of atomic-scale spins act like a single, disciplined antenna, generating microwave signals that are both powerful and remarkably long lived. Instead ...

This study is led by Dr. Jie Li et al. (Institute of Optics and Quantum Information, School of Physics, Zhejiang University). They reveal a new mechanism for preparing microwave squeezed vacuum states ...

Physicists have coaxed a cloud of quantum spins into doing something that should not happen in ordinary materials: they light up with microwaves and simply keep going. Instead of fading away, the ...
