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...

QUIC talk: Permutation-invariant quantum codes with Heisenberg ferromagnets
内容： A quantum code is a subspace of a Hilbert space of a physical system chosen to be correctable against a given class of errors, where information can be encoded. Ideally, the quantum code lies w...

Quantum Journal Club： Discrete-phase-randomized coherent state source and its ap
内容： Coherent state photon sources are widely used in quantum information processing. In many applications, a coherent state is functioned as a mixture of Fock states by assuming its phase is contin...
