Quantum Journal Club: Observation of quantum state collapse and revival due to t
内容： To create and manipulate non-classical states of light for quantum information protocols, a strong, nonlinear interaction at the singlephoton level is required. One approach to the generation o...

Quantum Journal Club: Quantum Discord Cannot Be Shared
内容： Bohr proposed that the outcome of a measurement becomes objective and real, and, hence, classical, when its results can be communicated by classical means. In this work we revisit Bohr’s postu...

Quantum Journal Club: Storage and retrieval of single photons transmitted betwee
内容： An elementary quantum network operation involves storing a qubit state in an atomic quantum memory node, and then retrieving and transporting the information through a single photon excitation ...

Quantum Journal Club: Teleportation of entanglement over 143 km
内容： As a direct consequence of the no-cloning theorem [1], the deterministic amplification as in classical communication is impossible for quantum states. This calls for more advanced techniques in...

Quantum Journal Club: Local detection of quantum correlations with a single trap
内容： Quantum correlations are at the heart of quantum information science1–3. Their detection usually requires access to all the correlated subsystems4,5. However, in many realistic scenarios this ...
