Techworld.com – OS and Servers News – Quantum computer to debut next week
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 stated aim is to eventually produce commercially available quantum computers that can be used online or shipped to computer rooms, where they will solve intractable and expensive problems such as financial optimisation.
It has been predicted that quantum computing will make current computer security obsolete, cracking any current cryptography scheme by providing an unlimited amount of simultaneous processing resources. Multiple quantum states exist at the same time, so every quantum bit or “qubit” in such a machine is simultaneously 0 and 1. D-Wave’s prototype has only 16 qubits, but systems with hundreds of qubits would be able to process more inputs than there are atoms in the universe. [More]
