Quantum Journal Club: Degree Distribution in QuantumWalks on Complex Networks
内容： In this theoretical study, we analyze quantum walks on complex networks, which model network-based processes ranging from quantum computing to biology and even sociology. Specifically, we analy...

Qunatum Journal Club: Storage and retrieval of ultrafast single photons using a
内容： We report the storage and retrieval of single photons, via a quantum memory, in the optical phonons of room-temperature bulk diamond. The THz-bandwidth heralded photons are generated by spontan...

Qunatum Journal Club: Enhanced Quantum Interface with Collective Ion-Cavity Coup
内容： We prepare a maximally entangled state of two ions and couple both ions to the mode of an optical cavity. The phase of the entangled state determines the collective interaction of the ions with...

Quantum Journal Club: Quantum teleportation of multiple degrees of freedom of a
内容： Quantumteleportation1 provides a ‘disembodied’way to transfer quantum states fromone object to another at a distant location, assisted by previously shared entangled states and a classical co...

Phase, interference and computation beyond quantum theory
内容： A quantum bit is qualitatively different from a classical bit as it allows for the coherent super-position of possibilities, which demonstrate different behaviours depending on the phase betwee...
