Preparing High-Fidelity Thermofield Double States
Brian J. J. Khor, Nadie LiTenn, Martin Sasieta +1
A major promise of quantum computers is the controlled preparation of many-body quantum states beyond the reach of efficient classical computation. Among the most important targets…
Confinement and Kink Entanglement Asymmetry on a Quantum Ising Chain
Brian J. J. Khor, D. M. Kürkçüoglu, T. J. Hobbs +2
In this work, we explore the interplay of confinement, string breaking and entanglement asymmetry on a 1D quantum Ising chain. We consider the evolution of an initial domain wall a…
Measurement Induced Chirality II: Diffusion and Disorder
Brian J J Khor, Matthew Wampler, Gil Refael +1
Repeated quantum measurements can generate effective new non-equilibrium dynamics in matter. Here we combine such a measurement driven system with disorder. In particular, we inves…
Stirring by Staring: Measurement Induced Chirality
Matthew Wampler, Brian J. J. Khor, Gil Refael +1
In quantum mechanics, the observer necessarily plays an active role in the dynamics of the system, making it difficult to probe a system without disturbing it. Here, we leverage th…
Engineering many-body quantum Hamiltonians with non-ergodic properties using quantum Monte Carlo
Nyayabanta Swain, Ho-Kin Tang, Darryl Chuan Wei Foo +5
We present a computational framework to identify Hamiltonians of interacting quantum many-body systems that host non-ergodic excited states. We combine quantum Monte Carlo simulati…
