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."
