Uniform process tensor approach for the calculation of multi-time correlation functions of non-Markovian open systems

Matteo Garbellini, Konrad Mickiewicz, Valentin Link +2

The process tensor framework to open quantum systems provides the most general description of multi-time correlations in non-Markovian quantum dynamics. A compressed representation…

Optimizing the dynamical preparation of quantum spin lakes on the ruby lattice

DinhDuy Vu, Dominik S. Kufel, Jack Kemp +3

Quantum spin liquids are elusive long-range entangled states. Motivated by experiments in Rydberg quantum simulators, recent excitement has centered on the possibility of dynamical…

Entanglement estimation of Werner states with a quantum extreme learning machine

Hajar Assil, Abderrahim El Allati, Gian Luca Giorgi

Quantum Extreme Learning Machines (QELMs) have emerged as a potent tool for various quantum information processing tasks. We present a QELM protocol for estimating the amount of en…

Spectral properties and coding transitions of Haar-random quantum codes

Grace M. Sommers, J. Alexander Jacoby, Zack Weinstein +2

A quantum error-correcting code with a nonzero error threshold undergoes a mixed-state phase transition when the error rate reaches that threshold. We explore this phase transition…

Tunable Magnetic Order in Chiral Coupled Spin Chains

Rafael D. Soares, J. M. Viana Parente Lopes, Hugo Terças

We obtain the ground-state phase diagram of two spin chains consisting in a set two-level systems asymmetrically coupled to an XX chain through a chiral interaction. The interactio…
