Provably Optimal Quantum Circuits with Mixed-Integer Programming
Harsha Nagarajan, Zsolt Szabó
We present a depth-aware optimization framework for quantum circuit compilation that unifies provable optimality with scalable heuristics. For exact synthesis of a target unitary,…

Long-term stability of driven quantum systems and the time-dependent Bloch equation
Zsolt Szabó, Kazuya Yuasa, Daniel Burgarth
This study looks at the finite-dimensional adiabatic evolution influenced by weak perturbations, extending the analysis to the asymptotic time limit. Beginning with the fundamental…

Robust quantification of spectral transitions in perturbed quantum systems
Zsolt Szabó, Stefan Gehr, Paolo Facchi +3
A quantum system subject to an external perturbation can experience leakage between uncoupled regions of its energy spectrum separated by a gap. To quantify this phenomenon, we pre…
