Enhancing quantum sensing sensitivity by a quantum memory
内容： In quantum sensing, precision is typically limited by the maximum time interval over which phase can be accumulated. Memories have been used to enhance this time interval beyond the coherence l...

Quantum Journal Club: Extending the lifetime of a quantum bit with error correction in superconducting circuits
内容： Quantum error correction (QEC) can overcome the errors experienced by qubits1 and is therefore an essential component of a future quantum computer. To implement QEC, a qubit is redundantly enco...

Quantum Journal Club: Hong-Ou-Mandel Interference between Two Deterministic Collective Excitations in an Atomic Ensemble
内容： We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg blockade we cre...

Small Unextendible Sets of MUBs
内容： In quantum information, Mutually Unbiased Bases (MUBs) correspond to sets of pairwise complementary observables. The maximal number of such bases in a system of dimension d is d+1, and construc...
