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…

Probing quantum thermalization of a disordered dipolar spin ensemble with discrete time-crystalline order
Joonhee Choi, Hengyun Zhou, Soonwon Choi +8
We investigate thermalization dynamics of a driven dipolar many-body quantum system through the stability of discrete time crystalline order. Using periodic driving of electronic s…
