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…
