Quantum circuit algorithm for topological invariants of second order topological many-body quantum magnets
Sebastián Domínguez-Calderón, Marcel Niedermeier, Jose L. Lado +1
Topological quantum matter represents a flexible playground to engineer unconventional excitations. While non-interacting topological single-particle systems have been studied in d…
Solving the Gross-Pitaevskii equation on multiple different scales using the quantics tensor train representation
Marcel Niedermeier, Adrien Moulinas, Thibaud Louvet +2
Solving partial differential equations of highly featured problems represents a formidable challenge, where reaching high precision across multiple length scales can require a proh…
Quantum computing topological invariants of two-dimensional quantum matter
Marcel Niedermeier, Marc Nairn, Christian Flindt +1
Quantum algorithms provide a potential strategy for solving computational problems that are intractable by classical means. Computing the topological invariants of topological matt…
Simulating the quantum Fourier transform, Grover's algorithm, and the quantum counting algorithm with limited entanglement using tensor-networks
Marcel Niedermeier, Jose L. Lado, Christian Flindt
Quantum algorithms reformulate computational problems as quantum evolutions in a large Hilbert space. Most quantum algorithms assume that the time-evolution is perfectly unitary an…
