Efficient Refocussing of One Spin and Two Spin Interactions for NMR Quantum Computation
arXiv:quant-ph/9905008 · doi:10.1006/jmre.1999.1890
Abstract
The use of spin echoes to refocus one spin interactions (chemical shifts) and two spin interactions (spin-spin couplings) plays a central role in both conventional NMR experiments and NMR quantum computation. Here we describe schemes for efficient refocussing of such interactions in both fully and partially coupled spin systems.
