Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Learning Feynman Diagrams with Tensor Trains
Yuriel Nunez-Fernandez, Matthieu Jeannin, Philipp T. Dumitrescu +4
We use tensor network techniques to obtain high order perturbative diagrammatic expansions for the quantum many-body problem at very high precision. The approach is based on a tens…
Realizing a dynamical topological phase in a trapped-ion quantum simulator
Philipp T. Dumitrescu, Justin Bohnet, John Gaebler +6
Nascent platforms for programmable quantum simulation offer unprecedented access to new regimes of far-from-equilibrium quantum many-body dynamics in (approximately) isolated syste…
Planckian Metal at a Doping-Induced Quantum Critical Point
Philipp T. Dumitrescu, Nils Wentzell, Antoine Georges +1
We numerically study a model of interacting spin- electrons with random exchange coupling on a fully connected lattice. This model hosts a quantum critical point separating tw…
Quantum Quasi-Monte Carlo algorithm for out-of-equilibrium Green functions at long times
Corentin Bertrand, Daniel Bauernfeind, Philipp T. Dumitrescu +3
We extend the recently developed Quantum Quasi-Monte Carlo (QQMC) approach to obtain the full frequency dependence of Green functions in a single calculation. QQMC is a general app…
Quantum Quasi-Monte Carlo Technique for Many-Body Perturbative Expansions
Marjan Maček, Philipp T. Dumitrescu, Corentin Bertrand +3
High order perturbation theory has seen an unexpected recent revival for controlled calculations of quantum many-body systems, even at strong coupling. We adapt integration methods…
