Overcoming frequency resolution limits using a solid-state spin quantum sensor
Qingyun Cao, Genko T. Genov, Yaoming Chu +4
The ability to determine precisely the separation of two frequencies is fundamental to spectroscopy, yet the resolution limit poses a critical challenge: distinguishing two incoher…
Quantum Memory Enhanced Multipoint Correlation Spectroscopy for Statistically Polarized NMR
Tobias Spohn, Nicolas Staudenmaier, Philipp J. Vetter +6
Nuclear magnetic resonance spectroscopy with solid-state spin sensors is a promising pathway for the detection of nuclear spins at the micro- and nanoscale. Although many nanoscale…
High-Fidelity Single-Shot Readout and Selective Nuclear Spin Control for a Spin-1/2 Quantum Register in Diamond
Prithvi Gundlapalli, Philipp J. Vetter, Genko Genov +5
Quantum networks offer a way to overcome the size and complexity limitations of single quantum devices by linking multiple nodes into a scalable architecture. Group-IV color center…
Robust GHz-range AC Magnetometry with an ensemble of NV Centers in Diamond using Concatenated Continuous Dynamical Decoupling
Takuya Kitamura, Genko Genov, Alon Salhov +5
Sub-picotesla level magnetometry has been demonstrated using negatively-charged nitrogen-vacancy (NV) centers in diamond by increasing the number of spins simultaneously used for s…
High-Fidelity Electron Spin Gates for Scaling Diamond Quantum Register
Timo Joas, Florian Ferlemann, Roberto Sailer +9
Diamond is a promising platform for quantum information processing as it can host highly coherent qubits that could allow for the construction of large quantum registers. A prerequ…
Robust Noise Suppression and Quantum Sensing by Continuous Phased Dynamical Decoupling
Daniel Louzon, Genko T. Genov, Nicolas Staudenmaier +5
We propose and demonstrate experimentally continuous phased dynamical decoupling (CPDD), where we apply a continuous field with discrete phase changes for quantum sensing and robus…
