Near-optimal quantum simulation of lattice Lindbladian dynamics
Rahul Trivedi, Xiehang Yu, Daniel Malz
We consider the problem of simulating dynamics under geometrically local Lindbladians acting on a lattice of qudits. We present an algorithm to approximate the time evolution under…
One-dimensional quantum Gibbs states in constant circuit depth
Saúl Pilatowsky-Cameo, Georgios Styliaris, Ainesh Bakshi +1
We prove that the Gibbs state of any spin chain can be exactly decomposed into a mixture of product states over contiguous blocks of qubits with bounded length, at any constant tem…
Collective decay of interacting bosons
Bennet Windt, Lorenzo Rossi, Alexander V. Poshakinskiy +2
We study a bosonic analog of the paradigmatic Dicke model of superradiance, comprising interacting bosonic modes subject to fully symmetric collective decay. Depending on the inter…
Algorithmic Locality via Provable Convergence in Quantum Tensor Networks
Siddhant Midha, Yifan F. Zhang, Daniel Malz +2
Belief propagation has recently emerged as a powerful framework for evaluating tensor networks in higher dimensions, combining computational efficiency with provable analytical gua…
Constraints on phantom codes from automorphism group bounds
Arthur S. Morris, Daniel Malz
Executing a logical quantum circuit fault-tolerantly incurs a large spacetime overhead. Recent work has proposed and investigated phantom codes, defined by the property that every…
Noise-induced contraction of MPO truncation errors in noisy random circuits and Lindbladian dynamics
Zhi-Yuan Wei, Joel Rajakumar, Jon Nelson +3
We study how matrix-product-operator (MPO) truncation errors evolve when simulating two setups: (1) 1D Haar-random circuits under either depolarizing noise or amplitude-damping noi…
