Fermionic Hamiltonian engineering with local control
Özgün Kum, Matthias Zipper, Ludwig Mathey +1
Quantum simulators enable the exploration of complex quantum phenomena in condensed-matter systems by reproducing their dynamics on controllable quantum devices. However, experimen…
Scalable Determination of Penalization Weights for Constrained Optimizations on Approximate Solvers
Edoardo Alessandroni, Sergi Ramos-Calderer, Michel Krispin +5
Quadratic unconstrained binary optimization (QUBO) provides problem formulations for various computational problems that can be solved with dedicated QUBO solvers, which can be bas…
A comprehensive benchmark of an Ising machine on the Max-Cut problem
Salwa Shaglel, Markus Kirsch, Marten Winkler +4
QUBO formulations of combinatorial optimization problems allow for solving them using various quantum heuristics. While large-scale quantum computations are currently still out of…
Compensating connectivity restrictions in quantum annealers via splitting and linearization techniques
Marcel Seelbach Benkner, Zorah Lähner, Vladislav Golyanik +2
Current quantum annealing experiments often suffer from restrictions in connectivity in the sense that only certain qubits can be coupled to each other. The most common strategy to…
Reducing the sampling complexity of energy estimation in quantum many-body systems using empirical variance information
Alexander Gresch, Uğur Tepe, Martin Kliesch
We consider the problem of estimating the energy of a quantum state preparation for a given Hamiltonian in Pauli decomposition. For various quantum algorithms, in particular in the…
Sound certification of memory-bounded quantum computers
Jan Nöller, Nikolai Miklin, Martin Kliesch +1
The rapid advancement of quantum hardware calls for the development of reliable methods to certify its correct functioning. However, existing certification tests often fall short:…
