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…
Quantum teleportation between simulated binary black holes
Aiden Daniel, Tanmay Bhore, Jiannis K. Pachos +2
The quantum description of a black hole predicts that quantum information hidden behind the event horizon can be teleported outside almost instantaneously. In this work, we demonst…
Ergodicity breaking in matrix-product-state effective Hamiltonians
Andrew Hallam, Jared Jeyaretnam, Zlatko PapiÄ
Thermalization and its breakdown in interacting quantum many-body systems are governed by mid-spectrum eigenstates, which are typically accessible only in small system sizes amenab…
Entanglement and apparent thermality in simulated black holes
Iason A. Sofos, Andrew Hallam, Jiannis K. Pachos
We investigate the apparent thermality of Hawking radiation in the semi-classical limit of quantum black holes using the mean-field limit of a chiral spin-chain simulator, which mo…
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…
