Solid state spin qubits are promising candidates for quantum information processing, but controlled interactions and entanglement in large, multi-qubit systems are currently difficult to achieve. We describe a method for programmable control of multi-qubit spin systems, in which individual nitrogen-vacancy (NV) centers in diamond nanopillars are coupled to magnetically functionalized silicon nitride mechanical resonators in a scanning probe configuration. Qubits can be entangled via interactions with nanomechanical resonators while programmable connectivity is realized via mechanical transport of qubits in nanopillars. To demonstrate the feasibility of this approach, we characterize both the mechanical properties and the magnetic field gradients around the micromagnet placed on the nanobeam resonator. Furthermore, we show coherent manipulation and mechanical transport of a proximal spin qubit by utilizing nuclear spin memory, and use the NV center to detect the time-varying magnetic field from the oscillating micromagnet, extracting a spin-mechanical coupling of 7.7(9) Hz. With realistic improvements the high-cooperativity regime can be reached, offering a new avenue towards scalable quantum information processing with spin qubits.

Hybrid quantum systems that couple spins to mechanical degrees of freedom allow for a variety of applications in quantum information processing, such as generating long-distance entanglement between solid-state spins via a mechanical resonator. Working towards this goal, we present a new platform consisting of magnetically functionalized, doubly-clamped silicon nitride beam resonators positioned close to diamond nanopillars. We report on measurements of coherent coupling between the electronic spin states of individual NV centers and the resonator motion, and show how this setup can be extended to generate programmable entanglement between many spins.

The continued emergence of large social network applications has introduced a scale of data and query volume that challenges the limits of existing data stores. However, few benchmarks accurately simulate these request patterns, leaving researchers in short supply of tools to evaluate and improve upon these systems. In this paper, we present a new benchmark, TAOBench, that captures the social graph workload at Meta. We open source workload configurations along with a benchmark that leverages these request features to both accurately model production workloads and generate emergent application behavior. We ensure the integrity of TAOBench's workloads by validating them against their production counterparts. We also describe several benchmark use cases at Meta and report results for five popular distributed database systems to demonstrate the benefits of using TAOBench to evaluate system …

Hybrid Quantum Systems With Nitrogen Vacancy Centers and Mechanical Resonators

Hybrid quantum systems involving coupled mechanical and spin degrees of freedom are promising candidates for applications in quantum metrology and quantum information processing. Specific examples range from sensitive magnetic field measurements to preparation of non-classical states of macroscopic objects and quantum transducers for mediating long range interactions between quantum bits. Nitrogen-vacancy (NV) centers in diamond represent a particularly promising spin system for these application. They feature long coherence times, well developed control methods, and a possibility of magnetic coupling to mechanical systems. However, achieving strong coupling between spin and mechanical degrees of freedom is challenging, as it requires a combination of large resonator zero point motion, magnetic field gradient, and mechanical quality factor within the same setting. This thesis presents two approaches for magnetic coupling between individual NV centers and mechanical oscillators. In the first approach, we demonstrate progress towards a high-cooperativity system with magnetically functionalized, doubly clamped silicon nitride resonators. We engineer high quality factor (Q > 10^5) resonators with large magnetic field gradients, and show how NVs can be integrated with this platform. Prospects for ground state cooling and quantum gate operations mediated by a mechanical bus are discussed. In the second approach, single micromagnets are trapped using a type-II superconductor nearby to spin qubits, enabling direct magnetic coupling between the two systems. Controlling the distance between the magnet and the …

We demonstrate a new mechanical transduction platform for individual spin qubits. In our approach, single micromagnets are trapped using a type-II superconductor in proximity of spin qubits, enabling direct magnetic coupling between the two systems. Controlling the distance between the magnet and the superconductor during cooldown, we demonstrate three-dimensional trapping with quality factors around 1× 10 6 and kHz trapping frequencies. We further exploit the large magnetic moment to mass ratio of this mechanical oscillator to couple its motion to the spin degrees of freedom of an individual nitrogen vacancy center in diamond. Our approach provides a new path towards interfacing individual spin qubits with mechanical motion for testing quantum mechanics with mesoscopic objects, realization of quantum networks, and ultrasensitive metrology.
