Abstract

Rabi nutations of a single nuclear spin in a solid were investigated. The investigations were carried out on a single electron and a single ¹³C nuclear spin of a single nitrogen-vacancy defect center in diamond. This system was employed for the implementation of quantum logical NOT and a conditional two-qubit gate (CROT). The results of the density matrix tomography show a gate fidelity up to 0.9.
