Quantum many-body mixed phase space revealed by hybrid feedback control
Hang Dong, Jie Ren, Andrew Hallam +9
The paper introduces a hybrid quantum‑classical feedback protocol that discovers and stabilizes long‑lived regular trajectories in a superconducting quantum processor, revealing a…
Unconventional Distance Scaling of Casimir-Polder Force between Atomic Arrays
Qihang Ye, Bing Miao, Lei Ying
Conventionally, dispersion forces mediated by quantum vacuum fluctuations are known to exhibit universal distance scalings, with retardation typically leading to a faster decay of…
ScarFinder: a detector of optimal scar trajectories in quantum many-body dynamics
Jie Ren, Andrew Hallam, Lei Ying +1
Mechanisms that give rise to coherent quantum dynamics, such as quantum many-body scars, have recently attracted much interest as a way of controlling quantum chaos. However, ident…
Liouvillian Spectral Transition in Noisy Quantum Many-Body Scars
Jin-Lou Ma, Zexian Guo, Yu Gao +2
Understanding the behavior of quantum many-body systems under decoherence is essential for developing robust quantum technologies. Here, we examine the fate of weak ergodicity brea…
Disorder-tunable entanglement at infinite temperature
Hang Dong, Jean-Yves Desaules, Yu Gao +13
Emerging quantum technologies hold the promise of unraveling difficult problems ranging from condensed matter to high energy physics, while at the same time motivating the search f…
Measuring Spectral Form Factor in Many-Body Chaotic and Localized Phases of Quantum Processors
Hang Dong, Pengfei Zhang, Ceren B. Dag +28
The spectral form factor (SFF) captures universal spectral fluctuations as signatures of quantum chaos, and has been instrumental in advancing multiple frontiers of physics includi…
