TL;DR: In this article, a geometrical solution to the problem of collecting photons from optically active defect centres in bulk diamond is presented, where integrated solid immersion lenses (SILs) are etched directly into the surface of diamond.

TL;DR: This work reports low error rate, GHz clocked QKD operation of an indium phosphide transmitter chip and a silicon oxynitride receiver chip—monolithically integrated devices using components and manufacturing processes from the telecommunications industry for large-scale deployment of quantum key distribution into future telecommunications networks.

TL;DR: This work has developed a new technique to fully characterize Multimode interference devices, which removes the need for phase-sensitive measurements and may find applications for a wide range of photonic devices.

TL;DR: In this article, an entanglement beam splitter using a quantum-dot spin in a double-sided optical microcavity was proposed, which can directly split a photon-spinproduct state into two constituent entangled states via transmission and reflection with high reliability and high quality.

TL;DR: In this article, it is shown that it is possible to fabricate an atomically precise linear array of single phosphorus bearing molecules on a silicon surface with the required dimensions for the fabrication of a silicon-based quantum computer.
