A fidelity metric for quantum annealing benchmarked by extreme scaling quantum Monte-Carlo simulations
Gabriel Gouraud, Miha Srdinsek, Xavier Waintal
Quantum annealers are supposed to follow adiabatically the ground state of a system as its Hamiltonian slowly interpolates between a trivial phase and a non-trivial one; the non-tr…

Replica Tensor Train
Miha Srdinsek, Gabriel Gouraud, Xavier Waintal
We describe a numerical many-body technique that is based on both tensor networks and quantum Monte Carlo. The variational ansatz is a tensor network that can harvest volume-law en…

Ergodicity breaking and deviation from Eigenstate Thermalisation in relativistic QFT
Miha Srdinšek, Tomaž Prosen, Spyros Sotiriadis
The validity of the ergodic hypothesis in quantum systems can be rephrased in the form of the eigenstate thermalisation hypothesis (ETH), a set of statistical properties for the ma…
