During the past decade the interaction of light with multiatom ensembles has attracted much
attention as a basic building block for quantum information processing and quantum state …

In order to establish an applicable system for advanced quantum information processing
based on the interaction between light and atoms, we have demonstrated a quantum …

We investigate the behavior of tripartite entanglement and entropy disorder in three non-
interacting qubits that are first prepared in a mixture state containing Greenberger–Horne …

Quantum non-demolition (QND) measurements improve sensitivity by evading
measurement back-action. The technique was first proposed to detect mechanical …

Many-body entangled states are key elements in quantum information science and quantum
metrology. One important problem in establishing a high degree of many-body …

This book is a self-contained guide to the world of quantum optical processes which
addresses different aspects relevant in quantum optics and quantum information. The basic …

We propose a scheme to implement a heralded quantum memory for single-photon
polarization qubits with a single atom trapped in an optical cavity. In this scheme, an injected …

We report successful manipulation of nonclassical atomic spin states. We apply an off-
resonant noncircularly-polarized light pulse to a measurement-induced squeezed spin state …

The continuous-variable controlled-Z gate is a canonical two-mode gate for universal
continuous-variable quantum computation. It is considered as one of the most fundamental …

An experimental success criterion for continuous-variable quantum teleportation and
memory is to surpass the limit of the average fidelity achieved by classical measure-and …
