Thermodynamic significance of QUBO encoding on quantum annealers

Emery Doucet, Zakaria Mzaouali, Reece Robertson +3

Quadratic unconstrained binary optimization (QUBO) is the standard interface to quantum annealers, yet a single constrained task admits many QUBO encodings whose penalty choices re…

Casimir effect with dielectric matter in salted water and implications at the cell scale

Larissa Inácio, Felipe S. S. Rosa, Astrid Lambrecht +2

The Casimir interaction in salted water contains a universal contribution of electromagnetic fluctuations that makes it of a longer range than previously thought. The universal con…

Harnessing subspace controllability: Dynamical generation of Dicke states in Heisenberg-coupled qubit arrays with a single local control

Vladimir M. Stojanovic, Tommaso Calarco, Andrea Muratori

We explore the feasibility of realizing Dicke states in qubit arrays with always-on isotropic Heisenberg coupling between adjacent qubits, assuming a single Zeeman-type control act…

Multiqubit Rydberg Gates for Quantum Error Correction

David F. Locher, Josias Old, Katharina Brechtelsbauer +4

Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead…

Simulating dynamics of the two-dimensional transverse-field Ising model: a comparative study of large-scale classical numerics

Joseph Vovrosh, Sergi Julià-Farré, Wladislaw Krinitsin +11

The quantum dynamics of many-qubit systems is an outstanding problem that has recently driven significant advances in both numerical methods and programmable quantum processing uni…

End-to-End Quantum Algorithm for Topology Optimization in Structural Mechanics

Leonhard Hölscher, Oliver Ahrend, Lukas Karch +5

Topology optimization is a key methodology in engineering design for finding efficient and robust structures. Due to the enormous size of the design space, evaluating all possible…
