Operator Growth from Global Out-of-time-order Correlators

Tianci Zhou, Brian Swingle

In the context of chaotic quantum many-body systems, we show that operator growth, as diagnosed by out-of-time-order correlators of local operators, also leaves a sharp imprint in…

Phase transition in von Neumann entanglement entropy from replica symmetry breaking

Shao-Kai Jian, Brian Swingle

We study the entanglement transition in monitored Brownian SYK chains in the large- limit. Without measurement the steady state -th Rényi entropy is obtained by summing over…

Chaos-protected locality

Shao-Kai Jian, Brian Swingle

Microscopic speed limits that constrain the motion of matter, energy, and information abound in physics, from the "ultimate" speed limit set by light to Lieb-Robinson speed limits…

Entanglement Phases in large-N hybrid Brownian circuits with long-range couplings

Subhayan Sahu, Shao-Kai Jian, Gregory Bentsen +1

We develop solvable models of large- hybrid quantum circuits on qubits and fermions with long-range power-law interactions and continuous local monitoring, which provide analyti…

Quantum error as an emergent magnetic field

Shao-Kai Jian, Chunxiao Liu, Xiao Chen +2

We investigate the effect of quantum errors on a monitored Brownian Sachdev-Ye-Kitaev (SYK) model featuring a measurement-induced phase transition that can be understood as a symme…

Measurement-induced purification in large-N hybrid Brownian circuits

Gregory Bentsen, Subhayan Sahu, Brian Swingle

Competition between unitary dynamics that scrambles quantum information non-locally and local measurements that probe and collapse the quantum state can result in a measurement-ind…

Quantum Gravity in the Lab: Teleportation by Size and Traversable Wormholes, Part II

Sepehr Nezami, Henry W. Lin, Adam R. Brown +6

In [1] we discussed how quantum gravity may be simulated using quantum devices and gave a specific proposal -- teleportation by size and the phenomenon of size-winding. Here we ela…
