JQI scientists, led by Professor Edo Waks, have performed an ultrafast logic gate on a photon, using a semiconductor quantum dot.

Arxiv – Controlled-NOT gate operating with single photons (10 pages) Technology Review – Cambridge physicists have built a quantum logic gate that combines a quantum dot that fires photons with a ...

A C-NOT logic gate requires two input photons. So the circuit works by zapping the quantum dot twice, generating two photons. These are identical because they’ve come from the same dot.

New quantum dot logic gates a step towards quantum computers A pair of articles in this week's edition of Science look at creating a form … ...

“We have demonstrated a system composed of a single quantum dot in a cavity that can be used to realize such a gate, and we demonstrated that two photons can be made to interact with each other via ...

Pointing to multicolored graphs showing supply and demand curves, Mr. Gates lectured about 160 corporate chieftains on the twisted economic logic that allowed many young Internet companies to ...

The first quantum-logic device made from silicon has been unveiled by researchers in Australia and Japan. Their controlled-not (CNOT) gate, which is a fundamental component of a quantum computer, was ...

Drivers wanting to head north on I-35 from eastbound I-80 will need to veer right instead of left with the opening of the mixmaster's flyover ramp.
