Open-System Adiabatic Quantum Search under Dephasing

Afaf El Kalai, Peter J. Eder, Christian B. Mendl ยท 2026

Adiabatic quantum algorithms must evolve slowly enough to suppress non-adiabatic transitions while remaining fast enough to be practical. In open systems, this trade-off is reshaped by decoherence. Foโ€ฆ
