Quantum Journal Club：Freezing motion-induced dephasing in an atomic-ensemble quantum memory
内容： Motion-induced dephasing is a dominant decoherence mechanism for atom-gas quantum memories. In this paper, we develop a new coherent manipulation technique which enables arbitrary engineering o...

Quantum Journal Club： Site-Resolved Imaging of Fermionic 6Li in an Optical Lattice
内容： We propose to encode a quantum bit of information in a superposition of coherent states of an oscillator, with four different phases. Our encoding in a single cavity mode, together with a prote...
