“Carbon nanotubes are the only quantum emitters that can emit single photons at room temperature and also at wavelengths used for telecommunications,” said Yuichiro Kato of the RIKEN Center for ...

Self-assembled semiconductor quantum dots (QDs) represent a three-dimensional confined nanostructure with discrete energy levels, which are similar to atoms. They are capable of producing highly ...

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...

For quantum communication to work, light sources must emit photons one at a time, not in random bunches. Several materials ...

Sparrow Quantum, a Copenhagen-based startup specializing in single-photon emitters suitable for a range of quantum technology applications, has raised €21.5 million in a series A funding round. Led by ...

Quantum Computing Inc. (NASDAQ:QUBT) announced on Tuesday the successful shipment of its first commercial entangled photon source. The company has delivered its first entangled photon source to a ...
