In the context of quantum technologies, the generation and manipulation of single photons
has become a key element for applications such as quantum communication and quantum …

The generation of entanglement between distant quantum systems is at the core of quantum
networking. In recent years, numerous theoretical protocols for remote-entanglement …

Photosynthesis is generally assumed to be initiated by a single photon,–from the Sun,
which, as a weak light source, delivers at most a few tens of photons per nanometre squared …

The faithful storage of a quantum bit (qubit) of light is essential for long-distance quantum
communication, quantum networking and distributed quantum computing. The required …

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its
fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions …

We present a formalism that accounts for the interaction of a local quantum system, such as
an atom or a cavity, with traveling pulses of quantized radiation. We assume Markovian …

An optical quantum memory can be broadly defined as a system capable of storing a
quantum state through interaction with light at optical frequencies. During the last decade …

We observe narrow band pairs of time-correlated photons of wavelengths 776 and 795 nm
from nondegenerate four-wave mixing in a laser-cooled atomic ensemble of Rb 87 using a …

We demonstrate high-fidelity, quantum nondemolition, single-shot readout of a
superconducting flux qubit in which the pointer state distributions can be resolved to below …

We study the interplay of photons interacting with an artificial atom in the presence of a
controlled dephasing. Such artificial atoms consisting of several independent scatterers can …
