"... a laser the size of a grain of rice, while investigating the use of semiconductor material fragments as components for quantum computing. The study was started to explore the quantum dots, and not lasers. Quantum dots act like single atoms, as components for quantum computers. The maser is a tiny, rice grain sized laser that is powered by a single electron from the artificial atoms called quantum dots.
Jason Petta, an associate professor of physics at Princeton and the lead author of the study, said, “It is basically as small as you can go with these single-electron devices.”"
I had never heard of "quantum computing" until recently. pl
