Operator Delocalization in Quantum Networks
Joonho Kim, Jeff Murugan, Jan Olle +1
We investigate the delocalization of operators in non-chaotic quantum systems whose interactions are encoded in an underlying graph or network. In particular, we study how fast ope…
Entanglement Diagnostics for Efficient Quantum Computation
Joonho Kim, Yaron Oz
We consider information spreading measures in randomly initialized variational quantum circuits and introduce entanglement diagnostics for efficient variational quantum/classical c…
Universal Effectiveness of High-Depth Circuits in Variational Eigenproblems
Joonho Kim, Jaedeok Kim, Dario Rosa
We explore the effectiveness of variational quantum circuits in simulating the ground states of quantum many-body Hamiltonians. We show that generic high-depth circuits, performing…
Unveiling operator growth in SYK quench dynamics
Matteo Carrega, Joonho Kim, Dario Rosa
We study non-equilibrium dynamics induced by a sudden quench of strongly correlated Hamiltonians with all-to-all interactions. By relying on a Sachdev-Ye-Kitaev (SYK) based quench…
