(EurekaAlert) Researchers at Stevens Institute of Technology have coaxed photons into interacting with one another with unprecedented efficiency — a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing. The team, led by Yuping Huang, an associate professor of physics and director of the Center for Quantum Science and Engineering, brings us closer to that goal with a nano-scale chip that facilitates photon interactions with much higher efficiency than any previous system.
The new method works at very low energy levels, suggesting that it could be optimized to work at the level of individual photons — the holy grail for room-temperature quantum computing and secure quantum communication.
