Photons a la Mode

The photodetectors in Alan Migdall’s lab often see no light at all, and that’s a good thing since he and his JQI (*) colleagues perform physics experiments that require very little light, the better to study subtle quantum effects. Their latest achievement, described here, is to develop a new way of counting photons to understand the sources and modes of light in modern physics experiments.

Quantum Information in Low Light

JQI researchers in the lab of Alan Migdall, demonstrate how one category of photo-detection system can make highly accurate readings of incoming information at the single-photon level by allowing the detector in some instances not to give a conclusive answer.

Quantum Dot Commands Light

All computers, even the future quantum versions, use logic operations or “gates,” which are the fundamental building blocks of computational processes. JQI scientists, led by Professor Edo Waks, have performed an ultrafast logic gate on a photon, using a semiconductor quantum dot.
