IBM Shows First Full Error Detection for Quantum Computers

Quantum computers must overcome the challenge of detecting and correcting quantum errors before they can fulfill their promise of sifting through millions of possible solutions much faster than classical computers. “With our recent four-qubit network, we built a system that allows us to detect both types of quantum errors,” says Jerry Chow, manager of experimental quantum computing at IBM’s Thomas J. Watson Research Center, in Yorktown Heights, N.Y. Chow, who, along with his IBM colleagues detailed their experiments in the 29 April issue of the journal Nature Communications, says, “This is the first demonstration of a system that has the ability to detect both bit-flip errors and phase errors” that exist in quantum computing systems. The IBM system consists of four quantum bits, or qubits, arranged in a 2-by-2 configuration on a chip measuring about 1.6 square centimeters ...
