Quantum-Inspired Algorithm for Classical Spin Hamiltonians Based on Matrix Product Operators
Ryo Watanabe, Joseph Tindall, Shohei Miyakoshi +1
We propose a tensor-network (TN) approach for solving classical optimization problems that is inspired by spectral filtering and sampling on quantum states. We first shift and scal…
Probabilistic Computing Optimization of Complex Spin-Glass Topologies
Fredrik Hasselgren, Max O. Al-Hasso, Amy Searle +2
Spin glass systems as lattices of disordered magnets with random interactions have important implications within the theory of magnetization and applications to a wide-range of har…
Simulating and Sampling from Quantum Circuits with 2D Tensor Networks
Manuel S. Rudolph, Joseph Tindall
Classical simulations of quantum circuits play a vital role in the development of quantum computers and for taking the temperature of the field. Here, we classically simulate vario…
Nonperturbative decay of bipartite discrete time crystals
Lennart Fernandes, Joseph Tindall, Dries Sels
We study prethermal time-crystalline order in periodically driven quantum Ising models on disorder-free decorated lattices. Using a tensor network ansatz for the state which reflec…
