Stable quantum, contradiction in
Quantum computing might 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. Quantum computers can still work with relatively large errors and
losses. It means that 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.
Errors are a bit problem in quantum
devices as they are sensitive to noise in their surroundings. It is
important that a useful device can be made from imperfect components. Quantum
computing was still in its early days, but it had the potential to
revolutionise computers because of its potential to be much more powerful
than current computers, especially in fields such as banking where security
of transactions is paramount.
