Efficient computation of real-time correlators using Pauli Propagation
Alexander F. Kemper, Raghav G. Jha, Arnab Bachhar +3
Pauli propagation has shown promise for classically simulating quantum dynamics by evolving observables directly in the Heisenberg picture. In this work, we investigate its use for…
Fast Scrambling in the Hyperbolic Ising Model
Goksu Can Toga, Abhishek Samlodia, Alexander F. Kemper
The paper studies how curvature in a hyperbolic (AdS2) Ising spin chain speeds up quantum information scrambling, using out-of-time-ordered correlators, Krylov complexity, and spec…
Magic and entanglement in 1+1-dimensional SU(2) lattice gauge theory
Raghav G. Jha, Goksu C. Toga, Jaber I. Taher +2
Entanglement and non-stabilizerness (magic) quantify two distinct departures of quantum systems from classical description: the former measures non-local correlations, while the la…
Quantum Ising Model on Dimensional Antide Sitter Space using Tensor Networks
Abhishek Samlodia, Simon Catterall, Alexander F. Kemper +2
We study the quantum Ising model on (2+1)-dimensional anti-de Sitter space using Matrix Product States (MPS) and Matrix Product Operators (MPOs). We explore the bulk phase diagram…
Information Propagation in Rydberg Arrays via Analog OTOC Calculations
Goksu Can Toga, Siva Darbha, Ermal Rrapaj +2
Out-of-time-order correlators (OTOCs) are the main tool for probing quantum chaos and scrambling, and have become crucial probes in many areas of quantum computing. However, the me…
CaRBM: A Fixed-Depth Quantum Algorithm with Partial Correction for Thermal State Preparation
Omar Alsheikh, A. F. Kemper, Ermal Rrapaj +2
We introduce the CaRBM algorithm for fixed-depth thermal state preparation. Our algorithm is based on thermal state purification and uses the Restricted Boltzmann Machine (RBM) blo…
