Spectral signatures of nonstabilizerness and criticality in infinite matrix product states
Andrew Hallam, Ryan Smith, Zlatko PapiÄ
The paper introduces a spectral transfer‑matrix method to study the stabilizer Rényi entropy in infinite matrix product states, revealing a distinct correlation length that diverge…
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…
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…
Tunable quantum Mpemba effect in long-range interacting systems
Andrew Hallam, Matthew Yusuf, Aashish A. Clerk +2
Symmetry plays a fundamental role in many-body systems, both in and out of equilibrium. The quantum Mpemba effect (QME) - a phenomenon where systems initially farther from equilibr…
Non-stabilizerness in kinetically-constrained Rydberg atom arrays
Ryan Smith, Zlatko PapiÄ, Andrew Hallam
Non-stabilizer states are a fundamental resource for universal quantum computation. However,despite broad significance in quantum computing, the emergence of "many-body" non-stabil…
Stirring the false vacuum via interacting quantized bubbles on a 5564-qubit quantum annealer
Jaka Vodeb, Jean-Yves Desaules, Andrew Hallam +7
False vacuum decay is a potential mechanism governing the evolution of the early Universe, with profound connections to non-equilibrium quantum physics, including quenched dynamics…
