IBM Q isn’t vaporware. It’s a project years-in-the-making that could help quantum computation reach its massive potential. The future of quantum computers may arrive sooner than you think. When news arrived of IBM’s move to offer the first commercially available universal quantum computer last week, it was characterized as a “handoff” from IBM Research to IBM Systems. According to the company’s CTO and vice president of quantum computing, technical strategy, and systems, Scott Crowder, that’s not entirely the case. “It’s not quite a ‘handoff,’ it’s really a partnership,” explained Crowder. “This is definitely a transition point from it being pure...

The actual problem that computer scientists threw at the D-Wave Two is pretty esoteric. To oversimplify it, they asked the machine to pick the optimum choice out of a large jumble of information with nearly 1,000 variables. Such optimization problems, which involve weighing multiple choices against each other, should be far, far easier for quantum computers to crunch. That's because the basis of quantum computation, the qubit, uses the odd physics of quantum mechanic to hold information as a zero, one, or a superposition of both. Again, to over-simplify things, this allows quantum computers to consider a vast number of...

Science The Future May Be Getting Close to Reality in Vancouver, With D-Wave and General Fusion March 18, 2014, 2:11 PM PDT By Liz Gannes   Vancouver is a land of scenic harbors, tall mountains and startups trying to harness the limits of physics.In town for the TED conference, I had the occasion to visit two such companies yesterday: D-Wave and General Fusion. D-Wave, a quantum computing company, is all about the very cold and the rather tiny. It has built enormous refrigerators that each house a single chip, laced with “qubits” that can be in the superposition of...

“[The company D-Wave] makes a new type of computer called a quantum computer that’s so radical and strange, people are still trying to figure out what it’s for and how to use it…. The supercooled niobium chip at the heart of the D-Wave Two has 512 qubits and therefore could in theory perform 2^512 operations simultaneously. That’s more calculations than there are atoms in the universe, by many orders of magnitude…. Naturally, a lot of people want one. This is the age of Big Data, and we’re burying ourselves in ­­information—search queries, genomes, credit-card purchases, phone records, retail transactions, social...

Twenty years before most scientists expected it, a commercial company has announceda quantum computer that promises to massively speed up searches and optimisation calculations. D-Wave of British Columbia has promised to demonstrate a quantum computer next Tuesday, that can carry out 64,000 calculations simultaneously (in parallel "universes"), thanks to a new technique which rethinks the already-uncanny world of quantum computing. But the academic world is taking a wait-and-see approach. D-Wave is the world's only "commercial" quantum computing company, backed by more than $20 million of venture capital (there are more commercial ventures in the related field of quantum cryptography). Its...
