Identifying different mechanisms in the control of a nitrogen–vacancy center system

摘要: Abstract The nitrogen–vacancy (NV) center system has shown great potential in quantum computing due to its long decoherence time at room temperature by encoding the qubit dressed states [28] . corresponding control mechanisms, which is expressed pathways linking initial and target states, can be naturally investigated with Hamiltonian-encoding observable-decoding (HE–OD) method interaction adiabatic representation. This proved fact that mechanisms change slightly different detunings, magnetic driving field intensities, dominant pathway always | g 〉 → d , as first two lowest states. Cases are diabatic orders of increase intensities. Tendencies amplitudes fields, fields detunings conditions, analyzed from Dyson series. HE–OD analysis show representation preferable employed a than state pair |0〉 − 1 under current Hamiltonian parameters.
