PARIS — Researchers from the University of Surrey, in the South East of England, claimed they have brought quantum computers one step closer. They demonstrated that it is now possible to make quantum computers in silicon rather than a vacuum.

Previous research, stated researchers, enabled to create some building blocks for a quantum computer by using atoms suspended in a vacuum. It was, however, not possible to make enough for a whole computers as scientists can hold a limited number of atoms in place for a short period of time.

By using atoms trapped in a silicon crystal, researchers said they proved that the quantum waves oscillate long enough for a computer operation. They now intend to produce a higher number of computer bits.

"These results are a significant step forward in the development of quantum computing," commented research leader Professor Ben Murdin from the University of Surrey. "We hope that this work will open up a new field of physics, where quantum coherence can be explored in solid crystals, but at the same time we have brought a scalable silicon quantum computer a step nearer."

For this project, researchers said they collaborated with scientists from University College London and Heriot-Watt University. They also used the free electron laser for Infrared experiments FELIX in the Netherlands.
