More efficient optical quantum gates

Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, quantum gates could be used for these purposes. ...

Laser bursts drive fastest-ever logic gates

A long-standing quest for science and technology has been to develop electronics and information processing that operate near the fastest timescales allowed by the laws of nature.

Researchers create self-assembled logic circuits from proteins

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital circuits that take advantage ...

Two teams use neutral atoms to create quantum circuits

Two teams of researchers working independently have shown the viability of using neutral atoms to create quantum circuits—both have published outlines of their work in the journal Nature. One of the groups, with members ...

Scientists develop novel DNA logic circuits

Based on the complementary base pairing rules, a variety of complex secondary structures can be designed and assembled to develop DNA molecular devices with specific functions which play an important role in diverse research ...

A new piece of the quantum computing puzzle

Research from the McKelvey School of Engineering at Washington University in St. Louis has found a missing piece in the puzzle of optical quantum computing.

A future of helpful engineered 'living' machines?

Engineered, autonomous machines combined with artificial intelligence have long been a staple of science fiction, and often in the role of villain like the Cylons in the "Battlestar Galactica" reboot, creatures composed of ...
