Quantum Journal Club： Discrete-phase-randomized coherent state source and its ap
Abstract: 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 co...

Quantum Journal Club: Ultrafast quantum random number generation based on quantu
Abstract: A quantum random number generator (QRNG) can generate true randomness by exploiting the fundamental indeterminism of quantum mechanics. Most approaches to QRNG employ single-photon detectio...

QUIC talk: Permutation-invariant quantum codes with Heisenberg ferromagnets
Abstract: 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 li...
