Defects with associated electron and nuclear spins in solid-state materials have a long
history relevant to quantum information science that goes back to the first spin echo …

Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

Practical quantum networks require interfacing quantum memories with existing channels
and systems that operate in the telecom band. Here we demonstrate low-noise, bidirectional …

In current long-distance communications, classical information carried by large numbers of
particles is intrinsically robust to some transmission losses but can, therefore, be …

Long-distance quantum teleportation and quantum repeater technologies require
entanglement between a single matter quantum bit (qubit) and a telecommunications …

Quantum entanglement is the central resource behind quantum information science, from
quantum computation and simulation, to enhanced metrology and secure communication …

We demonstrate efficient (<? format?>><? format?> 30%) quantum frequency conversion of
visible single photons (711 nm) emitted by a quantum dot to a telecom wavelength (1313 …

We demonstrate upconversion-assisted single-photon detection for the 1.55-μm
telecommunications band based on a periodically poled lithium niobate (PPLN) waveguide …

We report on the conversion to telecommunication wavelengths of single photons emitted by
a nitrogen-vacancy (NV) defect in diamond. By means of difference frequency generation …

We report on the realization and verification of quantum entanglement between a nitrogen-
vacancy electron spin qubit and a telecom-band photonic qubit. First we generate …
