Mechanical Spin Control of Nitrogen-Vacancy Centers in Diamond

We demonstrate direct coupling between phonons and diamond nitrogen-vacancy (NV) center spins by driving spin transitions with mechanically generated harmonic strain at room temperature. The amplitude of the mechanically driven spin signal varies with the spatial periodicity of the stress standing wave within the diamond substrate, verifying that we drive NV center spins mechanically. These spin-phonon interactions could offer a route to quantum spin control of magnetically forbidden transitions, which would enhance NV-based quantum metrology, grant access to direct transitions between all of the spin-1 quantum states of the NV center, and provide a platform to study spin-phonon interactions at the level of a few interacting spins.

“…These results pave a feasible route towards the long-standing goal of interrogating quantum mechanical phenomena at the macroscopic scale. Furthermore, the combination of the present optomechanical system with solid spin system [71] or atomic system [72,73] may provide a new platform of hybrid quantum optomechanics, e.g. to investigate non-demolition measurement of the phonon energy [71], sympathetic cooling of a mechanical oscillator [72], creation of a robust EPR-type of entanglement [74] between atomic ensemble and a mechanical resonator [75].…”

“…Ex-cept for optical and magnetic pluses, mechanical driving usually is applied to spin control. Significant progress in integrating NV centers with micro-electromechanical systems paves the way for spins coupled to mechanical resonators [13][14][15][16]. Using mechanical driving, MacQuarrie et al demonstrated direct spin-phonon interactions at room temperature as a means to drive magnetically forbidden spin transitions [17].…”

Nuclear-nuclear interaction mediated by a mechanically controlled nitrogen-vacancy-center spin in diamond

We propose a scheme to achieve nuclear-nuclear indirect interactions mediated by a mechanically driven nitrogen-vacancy (NV) center in diamond. Here we demonstrate two-qubit entangling gates and quantum-state transfer between two carbon nuclei in diamond. In such a system, the NV center interacts with a nearby nuclear spin via a dipole-dipole interaction. Under the quantum Zeno condition, the scheme is robust against decoherence caused by coupling between the NV center (nuclear spins) and the environment. Conveniently, precise control of dipole coupling is not required so this scheme is insensitive to fluctuating positions of the nuclear spins and the NV center. Our scheme provides a general blueprint for multi-nuclear-spin gates and for multi-party communication in a polygon geometry with each vertex occupied by a nuclear spin.
