NMR simulation of an eight-state quantum system - art. no. 032306

The propagation of excitation along a one-dimensional chain of atoms is sim ulated by means of nuclear magnetic resonance (NMR). The physical system us ed as an analog quantum computer is a nucleus of Cs-113 (spin 7/2) in a liq uid-crystalline matrix. First, a pseuodpure state of the spin system is pre pared. Then, the Hamiltonian of migration is simulated by using a special s even-frequency pulse. The dynamics is monitored by following the transfer o f population from one of the eight spin energy levels to the others.
