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...

Probabilistic simulations of quantum communication backward in time
内容： Like classical mechanics, quantum mechanics is a causal theory [1,2]--a theory that forbids sending messages from the future to the past. Still, one can simulate backward communication by posts...

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...

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...

Fermionic cellular automata and Quantum Fields
内容： We introduce Fermionic quantum cellular automata and describe the emergence of different geometries from their structure, under the assumptions of linearity, unitarity, locality, homogeneity an...

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...
