An anonymous reader writes Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology have reached a record low probability of error in processing quantum information with a single quantum bit (qubit) – the error rate first published small enough to meet the design requirements for building quantum computers viable. error by 10,000 logical operations is commonly agreed target error rate low enough to use correction protocols errors in a quantum computer, said Kenton Brown, who led the project as a postdoctoral researcher NIST. It is generally accepted that if the error rates are higher than you will introduce more error correction in your operations that you are able to correct. We have shown that we have good enough control over our operations that our single qubit error probability is 1 in 50 000 operations of logic.
