IBM paves the way quantum computer revolution

On Tuesday, IBM revealed that physicists at its Watson Research Center in Yorktown Heights, New York have made significant advances in the creation of “superconducting qubits,” one of several research fields that could eventually lead to a quantum computer that’s exponentially more powerful than today’s classical computers.

According to Matthias Steffen — who oversees Big Blue’s experimental quantum computing group — he and his team have improved the performance of superconducting qubits by a factor of two to four. “What this means is that we can really start thinking about much larger systems,” he tells Wired, “putting several of these quantum bits together and performing much larger error correction.”
