Quantum computer to debut next week
OS and Servers News
08 February 2007 Quantum computer to debut next week By Peter Judge, Techworld 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 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. Scientists in the world's many quantum science departments are looking anxiously at whether the demonstration - linked to a computer museum in Mountain View California, will vindicate their work or cast doubt upon it. "This is somewhat like claims of cold fusion," said Professor Andrew Steane of Oxford University's Centre for Quantum Computing. "I doubt that this computing method is substantially easier to achieve than any other." Others are more enthusiastic: "I'll be a bit of a sceptic till I see what they have done," said Professor Seth Lloyd of MIT. "But I'm happy these guys are doing it." Lloyd is one of the scientists who helped develop the "adiabatic" model of quantum computing which D-Wave's system exploits - a method which D-Wave believes will sidestep the problems which have restricted progress in quantum computing so far. http://www.techworld.com/opsys/news/...72&pagtype=all http://dwave.wordpress.com/2007/01/ [Pics] http://dwave.wordpress.com/2007/01/1...-announcement/ Info1 http://dwave.wordpress.com/2007/02/0...erested-folks/ info2 http://www.engadget.com/2007/02/08/q...-next-tuesday/

This is a picture of the Orion chip’s sample holder attached to one of our dilution fridges, ready to begin a cooldown.
The base temperature at which we operate (5mK, or 0.005 degrees above absolute zero) is about 500 times colder than interstellar space. In other words the difference between interstellar space and the base temperature of our fridges is about 5 times greater than the difference between room temperature (about 300K) and interstellar space (about 2.7K). ![]() This is a Leiden Cryogenics dilution fridge. These are beautiful, dependable machines that come highly recommended. We have three of these operational and haven’t had any problems with them in over 2 years of operation. A picture of one of the filter stages January 24, 2007 Posted by Geordie in World Domination, Superconducting Electronics. trackback Removing noise from input lines is very important. Here is a picture of one of the filtering stages. Each of the 128 input lines passes through a lumped element filter at this stage. ![]() Here’s a view of a 16-qubit processor mounted in its sample holder.

Mi risulta che il problema principale dei calcolatori quantistici, sia dotarli di unità di memoria in grande quantità.
Quanti qubit dovrebbe avere quel coso? EDIT: ho appena letto 16... e dato che, se ricordo bene, n qubit equivalgono a 2^n bit... direi che siamo ancora lontani dal VIC 20... (Comunque: 18 mesi fa erano solo 10...)

Ma sono già arrivati a questo punto!!!!
![]() così senza un passaggio intermedio per i computer ottici? aspetto e spero.... :stordita tra l'altro, avevo sentito che nessun sistema di criptazione attualmente usato era in grado di resistere alla potenza bruta di un computer quantistitico, è ora di tornare a nascondere i soldi sotto il materasso?? ![]() |
