Hyper-optimized tensor network contraction
Johnnie Gray, Stefanos Kourtis
Tensor networks represent the state-of-the-art in computational methods across many disciplines, including the classical simulation of quantum many-body systems and quantum circuit…
Nonuniversal Entanglement Level Statistics in Projection-driven Quantum Circuits
Lei Zhang, Justin A. Reyes, Stefanos Kourtis +3
We study the level-spacing statistics in the entanglement spectrum of output states of random universal quantum circuits where qubits are subject to a finite probability of project…
Obstacles to quantum annealing in a planar embedding of XORSAT
Pranay Patil, Stefanos Kourtis, Claudio Chamon +2
We introduce a planar embedding of the k-regular k-XORSAT problem, in which solutions are encoded in the ground state of a classical statistical mechanics model of reversible logic…
Ultra-slow dynamics in a translationally invariant spin model for multiplication and factorization
Lei Zhang, Stefanos Kourtis, Claudio Chamon +2
We construct a model of short-range interacting Ising spins on a translationally invariant two-dimensional lattice that mimics a reversible circuit that multiplies or factorizes in…
Observing spin fractionalization in the Kitaev spin liquid via temperature evolution of indirect resonant inelastic x-ray scattering
Gábor B. Halász, Stefanos Kourtis, Johannes Knolle +1
Motivated by the ongoing effort to search for high-resolution signatures of quantum spin liquids, we investigate the temperature dependence of the indirect resonant inelastic x-ray…
Quantum spin liquid at finite temperature: proximate dynamics and persistent typicality
I. Rousochatzakis, S. Kourtis, J. Knolle +2
Quantum spin liquids are long-range entangled states of matter with emergent gauge fields and fractionalized excitations. While candidate materials, such as the Kitaev honeycomb ru…
