Quantum Computer Implementation Remains an Extraordinary Challenge

How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the DiVincenzo criteria. The prescription is pretty clear at a glance; yet in practice the physical implementation of a full-scale universal quantum computer remains an extraordinary challenge.

‘Single-Photon-Switch’ Could Aid Development of Quantum Logic Gate

The idea to perform data processing with light, without relying on any electronic components, has been around for quite some time. In fact, necessary components such as optical transistors are available. However, up to now they have not gained a lot of attention from computer companies. This could change in the near future as packing densities of electronic devices as well as clock frequencies of electronic computers are about to reach their limits.

Researchers Find a Way to Control Quantum System of a Diamond

Computers do not necessarily have to perform error-free calculations in order to provide perfect results – they only need to correct their errors in a reliable way. And this will become even more important in the future, when it is hoped that quantum computers will solve some tasks several times faster than conventional PCs with computing processes that are very efficient but also prone to disturbances.

Defects in Diamond Hold Potential as Quantum Sensors of High Pressure Phenomena

New research shows that a remarkable defect in synthetic diamond produced by chemical vapor deposition allows researchers to measure, witness, and potentially manipulate electrons in a manner that could lead to new “quantum technology” for information processing. The study is published in the January 31, 2014, issue of Physical Review Letters.
