Separability gap and large deviation entanglement criterion
Jakub Czartowski, Konrad Szymański, Bartłomiej Gardas +2
For a given Hamiltonian on a multipartite quantum system, one is interested in finding the energy of its ground state. In the separability approximation, arising as a nat…
Approximate optimization, sampling and spin-glass droplets discovery with tensor networks
Marek M. Rams, Masoud Mohseni, Daniel Eppens +2
We devise a deterministic algorithm to efficiently sample high-quality solutions of certain spin-glass systems that encode hard optimization problems. We employ tensor networks to…
Quantum neural networks to simulate many-body quantum systems
Bartłomiej Gardas, Marek M. Rams, Jacek Dziarmaga
We conduct experimental simulations of many body quantum systems using a \emph{hybrid} classical-quantum algorithm. In our setup, the wave function of the transverse field quantum…
Quantum fluctuation theorem to benchmark quantum annealers
Bartłomiej Gardas, Sebastian Deffner
Near term quantum hardware promises unprecedented computational advantage. Crucial in its development is the characterization and minimization of computational errors. We propose t…
