A big step up: Two qubit computing

News: Computer Power    December 22, 2009
Step by step we’re moving closer to useful quantum computing. A big step, announced by the National Institute of Standards and Technology (NIST, USA), was the demonstration of a computing device using two qubits. Previous demonstrations by various researchers have used one qubit. In computing, two computational units are far more powerful than one. This [...]
