The single photon splitter, which is more formally known as a quantum dot single-photon turnstile device, is based on a structure that Dr. Petroff created seven years ago.

They also have the potential to offer higher levels of security. FCC staff members are recommending that digital receivers, or tuners, be mandatory in both high-definition TV sets and analog sets. Digital TV has been a disappointment.
