Sydney, Aug 7 - Quantum computing, the latest advance on the technology front that is still hedged with many ifs and buts, may be more stable than previously thought, according to the latest research.

Tom Stace, a University of Queensland (UQ) physicist, found that with even 50 percent loss of components, they could still work, unlike conventional computers, which would have broken down.

'Our results demonstrate that relatively large errors and losses can be tolerated, and so may confirm that quantum computers are genuinely feasible,' Stace said.

'What our work shows is theoretically a useful quantum device can be built even if up to 10 percent of its components suffer an error, or up to 50 percent of the components are completely lost.'

'Quantum devices are very sensitive to noise in their surroundings, and their performance can be greatly impaired by errors.
