Quantum Journal Club: Efficient Entanglement Criteria beyond Gaussian Limits Usi
内容： We present a formalism to derive entanglement criteria beyond the Gaussian regime that can be readily tested by only homodyne detection. The measured observable is the Einstein-Podolsky-Rosen (...

Quantum Journal Club: Far-field optical imaging and manipulation of individual s
内容： A fundamental limit to existing optical techniques for measurement and manipulation of spin degrees of freedom is set by diffraction, which does not allow spins separated by less than about a q...

Quantum Journal Club: Control and Coherence of the Optical Transition of Single
内容： We demonstrate coherent control of the optical transition of single nitrogen-vacancy defect centers in diamond. On applying short resonant laser pulses, we observe optical Rabi oscillations wit...

QUIC talk: Information complementarity: A new paradigm for decoding quantum inco
内容： The existence of observables that are incompatible or not jointly measurable is a characteristic feature of quantum mechanics, which lies at the root of a number of nonclassical phenomena, such...
