Quantum engineers have now demonstrated a fully controllable three‑qubit register on a silicon photonic chip, turning a ...

A device smaller than a grain of dust is emerging as a surprisingly powerful candidate to reshape how quantum computers are ...

From left: Cohen, Gopinath, Krueper in the lab. Their paper, “Realistic model of entanglement-enhanced sensing in optical fibers,” was published in Optics Express earlier this year. Research into ...

In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature. Photons are ...

A device smaller than a grain of dust may help unlock the kind of quantum computers people have only dreamed about. Built on ...

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This ...

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at ...

Professor Scott Diddams: Scott Diddams holds the Robert H. Davis Endowed Chair at the University of Colorado Boulder, where he is also Professor of Electrical Engineering and Physics. He carries out ...

Large quantum optical networks of tryptophan in protein architectures – the kinds found in mammalian brains, but also in all eukaryotes and even in some bacteria – influence their collective response ...
