Theory Of Optical Λ Transitions In The 15N -V- Center In Diamond: Role Of The Hyperfine Interaction

Abstract

We present a thorough derivation of the excited-state energy levels of the negatively charged 15N-V- center in diamond for the strong applied electric-field case. We show that in the 15N-V- center a spin nonconserving two-photon Λ transition exists that is mediated by the hyperfine interaction, which provides the possibility to write quantum information. Using second-order perturbation theory we obtain a Λ transition rate of the order of 10 MHz at room temperature, which allows for approximately 104 quantum logic operations within the spin coherence time τd (T=300 K) ≈ ms of the 15N-V- center. © 2009 The American Physical Society.
