Entanglement Barriers from Computational Complexity: Matrix-Product-State Approach to Satisfiability
Tim Pokart, Frank Pollmann, Jan Carl Budich
We approach the 3-SAT satisfiability problem with the quantum-inspired method of imaginary time propagation (ITP) applied to matrix product states (MPS) on a classical computer. Th…
Diffusion in quantum state preparation: From passive cooling to system-bath engineering
Tim Pokart, Lukas König, Sebastian Diehl +1
We investigate and compare two particle number-conserving protocols for the preparation of a topologically nontrivial state. The first is derived from thermally coupling the system…
Adiabatic preparation of a number-conserving atomic Majorana phase
Benjamin Michen, Tim Pokart, Jan Carl Budich
We construct a protocol to adiabatically prepare the ground state of a widely discussed number-conserving model Hamiltonian for ultracold atoms in optical lattices that supports Ma…
Geometrically Taming Dynamical Entanglement Growth in Purified Quantum States
Tim Pokart, Carl Lehmann, Jan Carl Budich
Entanglement properties of purified quantum states are of key interest for two reasons. First, in quantum information theory, minimally entangled purified states define the Entangl…
