Tel Aviv, Sept. 19 -- A breakthrough in diamond technology could bring quantum communication and ultra-sensitive sensors out of the lab and into real-world use.

Israeli and German scientists announced the development of a method to capture nearly all the light emitted by microscopic defects in diamonds--an advance that could make quantum devices faster, more reliable, and easier to integrate into existing systems.

Researchers at the Hebrew University of Jerusalem, in collaboration with Humboldt University in Berlin, focused on nitrogen-vacancy (NV) centres, tiny imperfections in diamond crystals that emit single particles of light, or photons, carrying quantum information.

These photons are essential for developing next-generation quan...
