An error-checking method that could prove crucial to the development of a practical quantum computer has been developed.
Physicists at the University of California, Santa Barbara, have discovered a new way to check how much the information stored inside a quantum computer has decayed. This is an impressive feat since measuring the state of a qubit normally destroys its quantum properties.
