Quantum Metrology with Strongly Interacting Spin Systems
Hengyun Zhou, Joonhee Choi, Soonwon Choi +10
Quantum metrology makes use of coherent superpositions to detect weak signals. While in principle the sensitivity can be improved by increasing the density of sensing particles, in…
Robust Dynamic Hamiltonian Engineering of Many-Body Spin Systems
Joonhee Choi, Hengyun Zhou, Helena S. Knowles +3
We introduce a new approach for the robust control of quantum dynamics of strongly interacting many-body systems. Our approach involves the design of periodic global control pulse…
Nanoscale NMR Spectroscopy using Self-Calibrating Nanodiamond Quantum Sensors
Jeffrey Holzgrafe, Qiushi Gu, Jan Beitner +3
Conventional nuclear magnetic resonance (NMR) spectroscopy relies on acquiring signal from a macroscopic ensemble of molecules to gain information about molecular structure and dyn…
Error Corrected Spin-State Readout in a Nanodiamond
Jeffrey Holzgrafe, Jan Beitner, Dhiren Kara +2
Quantum state readout is a key component of quantum technologies, including applications in sensing, computation, and secure communication. Readout fidelity can be enhanced by repe…
