Quantum Journal Club: Neutral Gas Sympathetic Cooling of an Ion in a Paul Trap
内容： A single ion immersed in a neutral buffer gas is studied. An analytical model is developed that gives a complete description of the dynamics and steady-state properties of the ions. An extensio...

QUIC talk: Measurement sharpness cuts nonlocality and contextuality in every phy
内容： Gathering data through measurements is at the basis of every experimental science. Ideally, measurements should be repeatable and, when extracting only coarse-grained data, they should allow th...

Quantum Nonlinear Optics Using Quantum Memory
内容： Large nonlinearity at the single-photon level can pave the way for the implementation of universal quantum gates. However, realizing large and noiseless nonlinearity at such low light levels ha...
