Quantum Journal Club: A near–quantum-limited Josephson traveling-wave parametric amplifier
Abstract: Detecting single–photon level signals—carriers of both classical and quantum information—is particularly challenging for low-energy microwave frequency excitations. Here we introduce a s...

Quantum Journal Club: Coherent and dynamic beam splitting based on light storage in cold atoms
Abstract: We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically induced t...
