Sub-Doppler forces for 137 Ba ions
Abstract: In this talk I present a theoretical study of calculating sub-Doppler forces for 137 Ba ions. The D1 transition line is employed for cooling line. Two cooling schemes are used: (i) Fg=1 - F...

A substate theorem in classical and quantum information theory with some applica
Abstract: Suppose P, Q are probability distributions on the same sample space. Their relative entropy is defined as S(P||Q) = \sum_i P(i) \log (P(i) / Q(i)). The relative entropy is an important info...

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...
