Dynamical Sensitivity Control of a single-spin quantum sensor.
Scientific reports, 2017Co-Authors: Andrii Lazariev, Silvia Arroyo-camejo, Ganesh Rahane, Vinaya Kumar Kavatamane, Gopalakrishnan BalasubramanianAbstract:The Nitrogen-Vacancy (NV) defect in diamond is a unique quantum system that offers precision sensing of nanoscale physical quantities at room temperature beyond the current state-of-the-art. The benchmark parameters for nanoscale magnetometry applications are Sensitivity, spectral resolution, and dynamic range. Under realistic conditions the NV sensors Controlled by conventional sensing schemes suffer from limitations of these parameters. Here we experimentally show a new method called dynamical Sensitivity Control (DYSCO) that boost the benchmark parameters and thus extends the practical applicability of the NV spin for nanoscale sensing. In contrast to conventional dynamical decoupling schemes, where π pulse trains toggle the spin precession abruptly, the DYSCO method allows for a smooth, analog modulation of the quantum probe’s Sensitivity. Our method decouples frequency selectivity and spectral resolution unconstrained over the bandwidth (1.85 MHz–392 Hz in our experiments). Using DYSCO we demonstrate high-accuracy NV magnetometry without |2π| ambiguities, an enhancement of the dynamic range by a factor of 4 · 103, and interrogation times exceeding 2 ms in off-the-shelf diamond. In a broader perspective the DYSCO method provides a handle on the inherent dynamics of quantum systems offering decisive advantages for NV centre based applications notably in quantum information and single molecule NMR/MRI.

Dynamical Sensitivity Control of a single-spin quantum sensor
arXiv: Quantum Physics, 2015Co-Authors: Andrii Lazariev, Silvia Arroyo-camejo, Ganesh Rahane, Vinaya Kumar Kavatamane, Gopalakrishnan BalasubramanianAbstract:The Nitrogen-Vacancy (NV) defect in diamond is a unique quantum system that offers precision sensing of nanoscale physical quantities beyond the current state-of-the-art. Here we present a method to Controllably encode the interactions in the population of the spin states, thereby introducing a way to Control the Sensitivity of a single spin as a continuum in contrast to free-evolution based methods. By adopting this feature we demonstrate high-accuracy NV magnetometry without 2pi ambiguities, enhance the dynamic range by a factor of 4*10^3 achieve interaction times exceeding 2 ms in off-the-shelf diamond. We perform nuclear spin-noise spectroscopy in the frequency domain by dynamically Controlling the NV spin's Sensitivity piecewise and in a smooth manner thereby precluding harmonic artefacts and undesired interactions. On a broader perspective dynamical Sensitivity Control provides an elegant handle on the inherent dynamics of quantum systems, while offering decisive advantages for NV centre applications notably in quantum Controls and single molecule NMR/MRI.
