Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

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 memory is essential for the development of many devices in quantum information
processing, including a synchronization tool that matches various processes within a …

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 …

We perform a review of various approaches to the implementation of quantum memories,
with an emphasis on activities within the quantum memory sub-project of the EU integrated …

We propose a quantum repeater protocol which builds on the well-known Duan-Lukin-Cirac-
Zoller (DLCZ) protocol [LM Duan, MD Lukin, JI Cirac, and P. Zoller, Nature (London) 414 …

Coherent and reversible mapping of quantum information between light and matter is an
important experimental challenge in quantum information science. In particular, it is an …

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

By harnessing aspects of quantum mechanics, communication and information processing
could be radically transformed. Promising forms of quantum information technology include …
