Probe Signatures of Quantum Chaos with Quantum Sensing
Isaías Vallejo-Fabila, Jing Yang
The spectral form factor (SFF), which is the Fourier transform of the two-point spectral correlation, is a fundamental diagnostics of quantum chaos. Nevertheless, its experimental…
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…
Exact Quantum Dynamics, Shortcuts to Adiabaticity, and Quantum Quenches in Strongly-Correlated Many-Body Systems: The Time-Dependent Jastrow Ansatz
Jing Yang, Adolfo del Campo
The description of strongly correlated quantum many-body systems far from equilibrium presents a fundamental challenge due to the vast amount of information it requires. We introdu…
Quantum Alchemy and Universal Orthogonality Catastrophe in One-Dimensional Anyons
Naim E. Mackel, Jing Yang, Adolfo del Campo
Many-particle quantum systems with intermediate anyonic exchange statistics are supported in one spatial dimension. In this context, the anyon-anyon mapping is recast as a continuo…
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…
