a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

Quantum technologies are cutting-edge systems that can process, transfer, or store information leveraging quantum mechanical ...

Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids.

COLLEGE PARK, MD – February 22, 2024 – Quantum computing company IonQ (NYSE: IONQ) today announced it has generated photons entangled with ions repeatedly and reproducibly, creating a quantum state ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

A recent article published in the journal Nature Communications demonstrates time-resolved fluorescence spectroscopy using entangled photon pairs from a continuous-wave laser, replacing ultrafast ...
