We review the current status of single-photon-source and single-photon-detector
technologies operating at wavelengths from the ultraviolet to the infrared. We discuss …

The distribution of quantum states over long distances is limited by photon loss.
Straightforward amplification as in classical telecommunications is not an option in quantum …

Quantum networks provide opportunities and challenges across a range of intellectual and
technical frontiers, including quantum computation, communication and metrology. The …

Quantum networks play an extremely important role in quantum information science, with
application to quantum communication, computation, metrology, and fundamental tests. One …

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 bring quantum networks into the real world, we would like to determine the
requirements of quantum network protocols including the underlying quantum hardware …

An efficient multimode quantum memory is a crucial resource for long-distance quantum
communication based on quantum repeaters. We propose a quantum memory based on …

Entanglement is the fundamental characteristic of quantum physics—much experimental
effort is devoted to harnessing it between various physical systems. In particular …

Many applications of quantum communication crucially depend on reversible transfer of
quantum states between light and matter. Motivated by rapid recent developments in theory …

Quantum communication is a method that offers efficient and secure ways for the exchange
of information in a network. Large-scale quantum communication,,,(of the order of 100 km) …
