A diamond nanowire single-photon source [PDF]

Nature Nanotechnology, 2010
The development of a robust light source that emits one photon at a time will allow new technologies such as secure communication through quantum cryptography. Devices based on fluorescent dye molecules, quantum dots and carbon nanotubes have been demonstrated, but none has combined a high single-photon flux with stable, room-temperature operation ...

Cascaded Kerr photon-blockade sources and applications in quantum key distribution

Scientific Reports, 2017
To raise the repetition rate, a single-photon source based on Kerr quantum blockade in a cascaded quantum system is studied. Using the quantum trajectory method, we calculate and simulate the photon number distributions out of a two-cavity system. A high

Single-photon Emission from an Acoustically-driven Lateral Light-emitting Diode [PDF]

, 2019
Single-photon sources are essential building blocks in quantum photonic networks, where quantum-mechanical properties of photons are utilised to achieve quantum technologies such as quantum cryptography and quantum computing.

Perfect single-photon sources

Scientific Reports
AbstractWe introduce the gapped coherent state in the form of a single-photon source (SPS) that consists of uncorrelated photons as a background, except that we demand that no two photons can be closer in time than a time gap $$t_\text{G}$$ t G .

Cavity enhanced telecom heralded single photons for spin-wave solid state quantum memories

New Journal of Physics, 2016
We report on a source of heralded narrowband ( $\approx 3$ MHz) single photons compatible with solid-state spin-wave quantum memories based on praseodymium doped crystals. Widely non-degenerate narrow-band photon pairs are generated using cavity enhanced

Deterministic single-photon source from a single ion

, 2009
We realize a deterministic single-photon source from one and the same calcium ion interacting with a high-finesse optical cavity. Photons are created in the cavity with efficiency (88 +- 17)%, a tenfold improvement over previous cavity-ion sources ...

Single-photon source characterization with twin infrared-sensitive superconducting single-photon detectors [PDF]

Journal of Applied Physics, 2007
We report on the high fidelity characterization, via spontaneous emission lifetime and g(2)(τ) measurements, of a cavity-coupled quantum dot single-photon source at 902nm using a pair of nanowire-based superconducting single-photon detectors (SSPDs).

Organic molecule single-photon sources

Oxford Open Materials Science, 2022
Abstract Since the onset of the 1990s, the development of single-molecule spectroscopy has led to the discovery of various quantum optical signatures in organic single molecules. The single-photon nature of an organic chromophore is of particular importance because of its potential as a nonclassical photon source at room temperature for ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
