Quantum computer chips edge closer to reality

Washington: In the quest for smaller, faster computer chips, researchers are now turning to quantum mechanics.

The work of Paul Berger, professor of computer engineering and physics and colleagues at Ohio State University (OSU) may one day enable faster, low-power computer chips. It could also lead to high-resolution cameras for security and public safety, and cameras that provide clear vision through bad weather.

The team fabricated a device called a tunnelling diode using the most common chip-making technique.

"We wanted to do this using only the tools found in the typical chip-makers toolbox," Berger said.

"Here we have a technique that manufacturers could potentially use to fabricate quantum devices directly on a silicon chip, side-by-side with their regular circuits and switches," he added.

The quantum device in question is a diode that will enable such devices to run on very little power.

The findings are slated for publication in the journal IEEE Electron Device Letters.
