Mechanical Control of a Single Nuclear Spin

Nuclear spins interact weakly with their environment and therefore exhibit long coherence times. This has led to use as memory qubits in quantum information platforms, where they are controlled via electromagnetic waves. Scaling up such platforms comes challenges terms of power efficiency, well cross-talk between devices. Here, we demonstrate coherent control a single nuclear spin using surface acoustic We mechanically driven Ramsey spin-echo sequences show that the retains its excellent properties. estimate this approach requires 2–3 orders magnitude less than more conventional methods. Furthermore, technique is scalable because possibility guiding waves reduced different channels. work demonstrates mechanical for complex sequences, offers an advantageous alternative standard spins, opens prospects incorporating interfaced hybrid architectures.Received 13 September 2021Revised 14 January 2022Accepted 21 2022DOI:https://doi.org/10.1103/PhysRevX.12.011056Published by American Physical Society under Creative Commons Attribution 4.0 International license.
