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 …

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 …

Quantum control is concerned with active manipulation of physical and chemical processes
on the atomic and molecular scale. This work presents a perspective of progress in the field …

Quantum light–matter interfaces are at the heart of photonic quantum technologies.
Quantum memories for photons, where non-classical states of photons are mapped onto …

Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

Storing and retrieving a quantum state of light on demand, without corrupting the information
it carries, is an important challenge in the field of quantum information processing. Classical …

Field-orthogonal temporal modes of photonic quantum states provide a new framework for
quantum information science (QIS). They intrinsically span a high-dimensional Hilbert space …

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 …

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 …

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