D-Wave Computer's Solution Raises More Questions

Does D-Wave's computer owe its high performance to bizarre quantum effects?   Photo courtesy of D-Wave Systems, Inc. An experimental computer made by a Canadian company has proved its ability to solve increasingly complex mathematical problems. But the question remains -- just how much of this calculating power is actually due to the strange properties of quantum mechanics? In theory, quantum computers can perform calculations far faster than their classical counterparts to solve incredibly com...
