Here's a 1997 paper on "quantum computing in the large" that I had been asking about:
http://www.media.mit.edu/physics/projects/spins/home.html "Neil Gershenfeld and Isaac Chuang have developed an entirely new approach to quantum computation that promises to solve many of these problems. Instead of carefully isolating a small number of qubits, we use a large thermal ensemble (such as a cup of coffee). Such a system has ~10^23 degrees of freedom; by applying RF pulses that excite nuclear magnetic resonances, we can create a tiny deviation from equilibrium that acts just like a much smaller number of pure qubits." -- Security Guru for Hire http://www.lightconsulting.com/~travis/ -><- GPG fingerprint: 9D3F 395A DAC5 5CCC 9066 151D 0A6B 4098 0C55 1484 --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
