Quasi-local Edge Mode in XXX Spin Chain/Circuit with Interaction Boundary Defect
Tomaž Prosen
We study the Heisenberg spin-1/2 model on a semi-infinite chain - or, equivalently, a trotterized unitary SU(2) symmetric six-vertex quantum circuit - with a boundary defect where…
Logarithmic growth of operator entanglement in a clean non-integrable circuit
Mao Tian Tan, Tomaž Prosen
We study a so-called semi-ergodic brickwork dual-unitary circuits where, in the infinite volume limit, the two-point correlation functions of single-site operators exhibit ergodic…
Random matrix perspective on probabilistic error cancellation
Leonhard Moske, Pedro Ribeiro, Tomaž Prosen +3
Probabilistic error cancellation is an attempt to reverse the effect of dissipative noise channels on quantum computers by applying unphysical channels after the execution of a qua…
Loop Charges and Fragmentation in Pairwise Difference Conserving Circuits
Pavel Orlov, Cheryne Jonay, Tomaž Prosen
In this work, we introduce a broad class of circuits, or quantum cellular automata, which we call 'pairwise-difference-conserving circuits' (PDC). These models are characterized by…
Dynamic scaling and Family-Vicsek universality in quantum spin chains
CÄtÄlin PaÅcu Moca, Balázs Dóra, Doru Sticlet +3
The Family-Vicsek scaling is a fundamental framework for understanding surface growth in non-equilibrium classical systems, providing a universal description of temporal surface ro…
Leading and beyond leading-order spectral form factor in chaotic quantum many-body systems across all Dyson symmetry classes
Vijay Kumar, Tomaž Prosen, Dibyendu Roy
We show the emergence of random matrix theory (RMT) spectral correlations in the chaotic phase of generic periodically kicked interacting quantum many-body systems by analytically…
