Scientists are learning to sculpt photons into powerful new forms, opening the door to high-capacity quantum technologies.

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely ...

Tokyo, November 2, 2023 — In a study published in Volume 20, Issue 4 of the journal Physical Review Applied on 16 October 2023, a team of researchers from Japan, led by Associate Professor Kaoru ...
