Optimal compression of constrained quantum time evolution
Maurits S. J. Tepaske, David J. Luitz, Dominik Hahn
The time evolution of quantum many-body systems is one of the most promising applications for near-term quantum computers. However, the utility of current quantum devices is strong…
Compressed quantum error mitigation
Maurits S. J. Tepaske, David J. Luitz
We introduce a quantum error mitigation technique based on probabilistic error cancellation to eliminate errors which have accumulated during the application of a quantum circuit.…
Field-tunable Berezinskii-Kosterlitz-Thouless correlations in a Heisenberg magnet
D. Opherden, M. S. J. Tepaske, F. Bärtl +10
We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk materia…
Optimal compression of quantum many-body time evolution operators into brickwall circuits
Maurits S. J. Tepaske, Dominik Hahn, David J. Luitz
Near term quantum computers suffer from a degree of decoherence which is prohibitive for high fidelity simulations with deep circuits. An economical use of circuit depth is therefo…
Three-dimensional isometric tensor networks
Maurits S. J. Tepaske, David J. Luitz
Tensor network states are expected to be good representations of a large class of interesting quantum many-body wave functions. In higher dimensions, their utility is however sever…
