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…
