A little light interaction leaves quantum physicists beaming

A team of physicists at the University of Toronto (U of T) have taken a step toward making the essential building block of quantum computers out of pure light. Their advance, described in a paper published this week in Nature ...

How losing information can benefit quantum computing

Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously ...

Researchers perform DNA computation in living cells

(Phys.org) —Chemists from North Carolina State University have performed a DNA-based logic-gate operation within a human cell. The research may pave the way to more complicated computations in live cells, as well as new ...

Laser-like photons signal major step towards quantum 'Internet'

The realisation of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'.

Researchers build switchable magnetic logic gate

(Phys.org)—A team of scientists from several research centers in South Korea, has succeeded in building a logic circuit that is based on switchable magnetism, rather than electronics. They describe their research and a ...

Researchers make first all-optical nanowire switch

(Phys.org)—Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1's and 0's were represented by bursts of light, instead of electricity.
