X-Message-Number: 21122 Date: Tue, 11 Feb 2003 07:40:24 -0500 From: Thomas Donaldson <> Subject: CryoNet #21107 - #21120 For Michael Price: From my own reading about quantum devices, the main thing that gives them an advantage is the computations which occur BEFORE the results are read out. If you read out the results you interfere with the quantum system, breaking the characteristics that allowed quantum computing. This doesn't mean you can't start it again on a different problem (or even the same one), just that like when you burst a bubble you have to blow another one. As for reading out the results none of the quantum computers I've read about seem to find that a problem. The problem seems to be that of working with a sufficient number of qubits to do meaningful calculations. As for differences between quantum coding and quantum computing, of course. But I was pointing out that at least one quantum device had been built by now, and so it would not be wise to assume that others won't be coming down the line. Best wishes and long long life for all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21122
