Numerical simulation of NMR/NQR experiments for the demonstration of quantum computing principles

The precision of solid-state nuclear magnetic/quadrupole resonance (NMR/NQR) in the manipulation of nuclear spins makes these techniques a natural means for the investigation of the principles of quantum computation. Following this idea, we have developed a software which simulates pulsed NMR/NQR experiments by employing both linearly and circularly polarized radiofrequency pulses and reproduces their results as are observed in laboratory. The purpose was twofold: first, the program allows to design pulse sequences which implement quantum gates and algorithms acting on spins’ states; on the other hand, the study of NMR/NQR spectra resulting from the implemented algorithms turns useful for the experimental identification of quantum correlations in real systems probed in laboratories. The details of the simulations and the code as well as the representative results will be presented.
