Integrable Digital Quantum Simulation: Generalized Gibbs Ensembles and Trotter Transitions
Eric Vernier, Bruno Bertini, Giuliano Giudici +1
The Trotter-Suzuki decomposition is a promising avenue for digital quantum simulation (DQS), approximating continuous-time dynamics by discrete Trotter steps of duration . Recen…

Entanglement Negativity and Mutual Information after a Quantum Quench: Exact Link from Space-Time Duality
Bruno Bertini, Katja Klobas, Tsung-Cheng Lu
We study the growth of entanglement between two adjacent regions in a tripartite, one-dimensional many-body system after a quantum quench. Combining a replica trick with a space-ti…
