D-Wave delivers on quantum demo promise

Your IT - Home IT

Canadian startup D-Wave delivered on its promise to demonstrate its quantum computer this week.

Although the demo was held at the Computer History Museum in Silicon Valley, the computer itself was back at the company's British Columbia headquarters.

"Quantum technology delivers precise answers to problems that can only be answered today in general terms. This creates a new and much broader dimension of computer applications, said CEO Herb Martin.

To this end, the major demonstration showed a search for a molecular structure to match a target (important for drug research) as well as the more prosaic - but also more readily understandable - solving of a sudoku puzzle.

The company has ambitious plans to press ahead from the initial 16-qubit chip to 32 qubits by the end of this year, 512 in the first quarter of 2008 and 1024 qubits in the third quarter. The company plans to ship its first products sometime next year.

There's no guarantee that the technology will scale, and some experts have yet to accept that D-Wave's device really is a quantum computer. CTO Geordie Rose has said that experts will be given a chance to inspect the system, and that the company's work will be subjected to peer review. D-Wave is a spinoff from the University of British Columbia.

Assuming the technology really does work, the chips could be produced by normal semiconductor foundries and would consume very little power.
