Quantum Journal Club: Quantum Discord and the Power of One Qubit
内容： We use quantum discord to characterize the correlations present in the model called deterministic quantum computation with one quantum bit (DQC1), introduced by Knill and Laflamme [Phys. Rev. L...

Quantum Journal Club: Detection and Control of Individual Nuclear Spins Using a
内容： We experimentally isolate, characterize, and coherently control up to six individual nuclear spins that are weakly coupled to an electron spin in diamond. Our method employs multipulse sequence...

Quantum Journal Club: Semi-device-independent bounds on entanglement
内容： Detection and quantification of entanglement in quantum resources are two key steps in the implementation of various quantum-information processing tasks. Here, we show that Bell-type inequalit...

Quantum Journal Club: Bose-Einstein Condensation of Atoms in a Uniform Potential
内容： We have observed the Bose-Einstein condensation of an atomic gas in the (quasi)uniform threedimensional potential of an optical box trap. Condensation is seen in the bimodal momentum distributi...
