Principles and Demonstrations of Quantum Information Processing by NMR Spectroscopy
T. F. Havel, S. S. Somaroo, C. -H. Tseng +1
This paper surveys our recent research on quantum information processing by nuclear magnetic resonance (NMR) spectroscopy. We begin with a geometric introduction to the NMR of an e…
