Four-spin Fredkin universal quantum valve model

Hennadii Horskyi, Vitalii Deibuk

There is considered the functioning of quantum logical Fredkin gate on nuclear magnetic resonance for case of 4 quantum bytes (QB) represented by nuclear spins. Optimal laws of nuclear spins coupling interaction distance variation which are necessary for accurate Fredkin gate functioning with superpositional states of QBs-system are ascertained. The influence of frequency noise and decoherentization due to broadening of energy levels caused by interaction with environment on Fredkin gate functioning are investigated
