Finite-bath projected ensembles in dual-unitary circuits
Rahul Arvind, Nicholas Hunter-Jones
We study the emergent randomness in projected ensembles generated by dual-unitary circuits. Specifically, we consider evolution by solvable dual-unitary brickwork circuits followed…
Local random quantum circuits converge to the Porter-Thomas distribution in polynomial depth
Aniruddha Sen, Nicholas Hunter-Jones
Porter-Thomas statistics are a characteristic feature of the output distribution of random quantum states and, more broadly, chaotic quantum many-body systems. Convergence to Porte…
Quantum Complexity Dynamics for Disjoint Subsystems
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +2
Quantum complexity has emerged as a natural probe of chaos, thermalization, and the black hole interior on timescales long after local observables have equilibrated. However, its t…
Ideal random quantum circuits pass the LXEB test
Nicholas Hunter-Jones, Jonas Haferkamp
We show that noiseless random quantum circuits pass the linear cross-entropy benchmark (LXEB) test with high probability. If the circuits are linear depth, and thus form unitary 4-…
