Moving beyond semiconductors for next-generation electric switches

Computers use switches to perform calculations. A complex film with "quantum wells"—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first ...

An optical switch based on a single nano-diamond

A recent study led by researchers of the ICFO (Institute of Photonic Sciences) demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. The scientific ...

MIT researchers build an all-optical transistor

Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations ...

Two stopped light pulses interact with each other

(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...

The impending revolution of low-power quantum computers

By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next revolution ...
