Abstract

We report on the reduced spectral diffusion of nitrogen vacancy centers in waveguides and cavities. We also design a cavity that provides both high quality factor and isolation from diamond surfaces.

Nitrogen Vacancy Centers in Diamond for Quantum Information Processing on Hybrid Platforms

Janik Wolters, Julia Kabuß, Max Strauß +2 more

The nitrogen vacancy (NV) defect center in diamond is one of the most promising candidates for future solid state quantum technologies. Starting with recent experiments on the demonstration of fundamental quantum effects, like the quantum Zeno effect on a single NV center, theoretical studies on the implementation of a fundamental cavity assisted two-qubit quantum gate are presented. These studies outline a route towards deterministic quantum information processing on a realistic solid state platform, considering in particular radiative dephasing and spectral diffusion.

Low-Charge-Noise Nitrogen-Vacancy Centers in Diamond Created Using Laser Writing with a Solid-Immersion Lens

High Resolution Image Download MS PowerPoint Slide We report on pulsed-laser-induced generation of nitrogen-vacancy (NV) centers in diamond facilitated by a solid-immersion lens (SIL). The SIL enables laser writing at energies as low as 5.8 nJ per pulse and allows vacancies to be formed close to a diamond surface without inducing surface graphitization. We operate in the previously unexplored regime, where lattice vacancies are created following tunneling breakdown rather than multiphoton ionization. We present three samples in which NV center arrays were laser-written at distances between ∼1 and 40 μm from a diamond surface, all presenting narrow distributions of optical linewidths with means between 62.1 and 74.5 MHz. The linewidths include the effect of long-term spectral diffusion induced by a 532 nm repump laser for charge-state stabilization, thereby emphasizing the particularly low-charge-noise environment of the created color centers. Such high-quality NV centers are excellent candidates for practical applications employing two-photon quantum interference with separate NV centers. Finally, we propose a model for disentangling power broadening from inhomogeneous broadening in the NV center optical linewidth.

Coupling of Nitrogen-Vacancy Centers to Photonic Crystal Cavities in Monocrystalline Diamond

Andrei Faraon, Charles Santori, Zhihong Huang +2 more

The zero-phonon transition rate of a nitrogen-vacancy center is enhanced by a factor of ∼70 by coupling to a photonic crystal resonator fabricated in monocrystalline diamond using standard semiconductor fabrication techniques. Photon correlation measurements on the spectrally filtered zero-phonon line show antibunching, a signature that the collected photoluminescence is emitted primarily by a single nitrogen-vacancy center. The linewidth of the coupled nitrogen-vacancy center and the spectral diffusion are characterized using high-resolution photoluminescence and photoluminescence excitation spectroscopy.
