Proving quantum computers feasible
November 27, 2012With a new contribution to probability theory, researchers show that relatively simple physical systems could yield powerful quantum computers.
10-year-old problem in theoretical computer science falls
July 30, 2012Interactive proofs — mathematical games that underlie much modern cryptography — work even if players try to use quantum information to cheat.
March 17, 2011If software companies design their algorithms with the sole intention of outperforming each other, the customer can be the loser.
