Finite speed of quantum scrambling with long range interactions
Chi-Fang Chen, Andrew Lucas
In a locally interacting many-body system, two isolated qubits, separated by a large distance , become correlated and entangled with each other at a time . This finit…

Operator growth bounds from graph theory
Chi-Fang Chen, Andrew Lucas
Let and be local operators in Hamiltonian quantum systems with degrees of freedom and finite-dimensional Hilbert space. We prove that the commutator norm $\lVert [A(t)…

Entanglement Wedge Reconstruction using the Petz Map
Chi-Fang Chen, Geoffrey Penington, Grant Salton
At the heart of recent progress in AdS/CFT is the question of subregion duality, or entanglement wedge reconstruction: which part(s) of the boundary CFT are dual to a given subregi…
