A team of researchers, led by IBM's Thomas J. Watson Center, has shown that a quantum computer can already help in the calculation of practical scientific problems that are inaccessible to today's classical computers. The "noise" and errors that accumulate still limit the applications of such computers, but the new study shows that, after adding a protocol that reduces these problems, a 127-cubit quantum computer is capable of simulating extremely complex physical states with high reliability. The results are published in the journal Nature.

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics to Alain Aspect, John F. Clauser and Anton Zeilinger for their experiments with entangled photons, establishing the violation of Bell's inequalities and becoming pioneers in quantum information science.
