In quantum computers improved 10x error correction - Future Tech. IBM researchers - led by Sergey Bravyi of the Watson Research Institute, and published in Nature.
This opens the doors to the so-called 'era of utility', that of quantum computers truly capable of working on hitherto impossible problems. Using new code, an algorithm to process the activities of qubits, the researchers managed to improve the correction of errors that accumulate on qubits by a factor of 10. An important progress that is part of IBM's roadmap to arrive at quantum processors with thousands of error-proof qubits in 4 or 5 years.
