An all-proton spin quantum gate in semiconductor spin magnetic resonance force system
View through CrossRef
We report on a kind of all-proton spin quantum gate realized by fabric silicon cantilever in a semiconductor spin magnetic resonance microscopy system. In the paper, the Rf pulse sequence control and the spin rotate frame system are adopted according to spin-lattice and spin-spin relaxation times,and the small resonance force, the sensitivity and the spin density matrix are studied. The results show that all-proton spin quantum gates have high Q controlling and detecting sensitivity, and gain the effective force oscillating through the resonance slice and fiber interferometer. The system has advantages of MRI and AFM characteristics. In addition, the calculation indicates that it is powerful tool of magnetic resonance force technology and useful way to achieve quantum computation and quantum information.
