Asymptotic Metrological Scaling and Concentration in Chaotic Floquet Dynamics
Astrid J. M. Bergman, Yunxiang Liao, Jing Yang
We study quantum sensing with Floquet chaotic dynamics generated by Haar random unitary gates. The metrological resources consist of three ingredients: A given initial state, a set…
Universal shot-noise limit for quantum metrology with local Hamiltonians
Hai-Long Shi, Xi-Wen Guan, Jing Yang
Quantum many-body interactions can induce quantum entanglement among particles, rendering them valuable resources for quantum-enhanced sensing. In this work, we derive a universal…
Large Deviations Beyond the Kibble-Zurek Mechanism
Federico Balducci, Mathieu Beau, Jing Yang +2
The Kibble-Zurek mechanism (KZM) predicts that the average number of topological defects generated upon crossing a continuous or quantum phase transition obeys a universal scaling…
Minimum-Time Quantum Control and the Quantum Brachistochrone Equation
Jing Yang, Adolfo del Campo
Minimum-time quantum control protocols can be obtained from the quantum brachistochrone formalism [Carlini, Hosoya, Koike, and Okudaira, Phys. Rev. Lett. 96, 06053, (2006)]. We poi…
