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 …

This paper reviews recent efforts to realize a high‐efficiency memory for optical pulses using
slow and stored light based on electromagnetically induced transparency (EIT) in …

Entanglement is a striking feature of quantum mechanics and an essential ingredient in most
applications in quantum information. Typically, coupling of a system to an environment …

Entanglement is an essential property of multipartite quantum systems, characterized by the
inseparability of quantum states of objects regardless of their spatial separation. Generation …

We study experimentally the fundamental limits of sensitivity of an atomic radio-frequency
magnetometer. First, we apply an optimal sequence of state preparation, evolution, and the …

The basic idea of squeezing can be understood by considering the quantum harmonic
oscillator, familiar from undergraduate quantum mechanics. Squeezing is best visualized by …

Quantum teleportation is a key ingredient in quantum networks, and one of the building
blocks for quantum computation,. Teleportation between distant material objects using light …

A quantum memory for light is a key element for the realization of future quantum information
networks,,. Requirements for a good quantum memory are versatility (allowing a wide range …

Up to now, the lifetime of experimentally demonstrated entangled states has been limited
due to their fragility under decoherence and dissipation. Therefore, they are created under …

We describe a new kind of phase-preserving quantum amplifier which utilizes dissipative
interactions in a parametrically coupled three-mode bosonic system. The use of dissipative …
