Light-based quantum circuit does basic maths Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum ...

With fellow physics professor Thad Walker, Saffman successfully used neutral atoms to create what is known as a controlled-NOT (CNOT) gate, a basic type of circuit that will be an essential element of ...

MADISON — Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the University of Wisconsin-Madison created an atomic circuit ...

Computers have become vastly more complex than 8- and 16-bit machines of yesteryear, which had the advantage of being much simpler to program than their modern descendants. That's what led Konstantin ...

A team of Stanford University engineers has developed a circuit board, and its underlying chips, that simulates the activity of the human brain 9,000 times faster than a personal computer and is ...
