Highly directional single-photon source [PDF]

open access: yesNanophotonics, 2023
Single-photon emitters are a pivotal element in quantum technologies, but the generation of single photons along well-defined directions generally involves sophisticated configurations.

Optical fibre-based single photon source using InAsP quantum dot nanowires and gradient-index lens collection [PDF]

open access: yesScientific Reports, 2021
We present a compact, fibre-coupled single photon source using gradient-index (GRIN) lenses and an InAsP semiconductor quantum dot embedded within an InP photonic nanowire waveguide. A GRIN lens assembly is used to collect photons close to the tip of the

Effect of loss on multiplexed single-photon sources

open access: yesNew Journal of Physics, 2015
An on-demand single-photon source is a key requirement for scaling many optical quantum technologies. A promising approach to realize an on-demand single-photon source is to multiplex an array of heralded single-photon sources using an active optical ...

Room-temperature single-photon source with near-millisecond built-in memory [PDF]

open access: yesNature Communications, 2021
Room-temperature single photon sources with memory capabilities are promising for quantum information processing, but are currently limited in their memory time or photon purity. Here, the authors report single photon emission with good antibunching from

An all-silicon single-photon source by unconventional photon blockade. [PDF]

open access: yesSci Rep, 2015
The lack of suitable quantum emitters in silicon and silicon-based materials has prevented the realization of room temperature, compact, stable, and integrated sources of single photons in a scalable on-chip architecture, so far.

Pure single photons from a trapped atom source

open access: yesNew Journal of Physics, 2016
Single atoms or atom-like emitters are the purest source of single photons, they are intrinsically incapable of multi-photon emission. To demonstrate this degree of photon number-state purity we have realized a single-photon source using a single ion ...

A single-photon source based on topological bulk cavity [PDF]

open access: yesLight: Science & Applications
Topological photonics offers the potential to develop quantum light sources with inherent robustness against structural disorders. To date, topologically protected edge or corner states have been investigated for this purpose.

Time-bin encoded quantum key distribution over 120 km with a telecom quantum dot source [PDF]

open access: yesLight: Science & Applications
Quantum key distribution (QKD) with deterministic single photon sources has been demonstrated over intercity fiber and free-space channels. The previous implementations relied mainly on polarization encoding schemes, which are susceptible to ...

Deterministic and highly indistinguishable single photons in the telecom C-band [PDF]

open access: yesNature Communications
Quantum dots are promising candidates for deterministic single-photon sources, yet achieving high photon indistinguishability at telecom wavelengths remains a critical challenge.

Single atom photon pair source [PDF]

open access: yesEPJ Web of Conferences, 2022
Sources of entangled photon pairs are a crucial ingredient for many applications in quantum information and communication. Of particular interest are narrow-band sources with bandwidths that are compatible with solid state systems such as atomic media ...
