Quantum Transistor Counts Photons

Posted November 15, 2007 8:11 AM

Containing about 1000 quantum dots, a novel quantum dot, optically-gated, field-effect transistor (QDOGFET) can accurately count one, two, or three photons at least 83% of the time. The device may find practical application in quantum key distribution (QKD) for encryption using single photons since it can operate at high temperatures and be integrated into electronics.

The preceding article is a "sneak peek" from Electronic Components, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Electronic Components today.

"...can accurately count one, two, or three photons at least 83% of the time."

What does it count the other 17% of the time? Sheep?
