Authors: Santos, Alan C. Journal: PHYSICAL REVIEW A Publication date: 2025/02/18 DOI: 10.1103/PhysRevA.111.022618 Abstract: Digitizing an adiabatic evolution is a strategy able to combine the good performance of gate-based quantum processors with the advantages of adiabatic algorithms, thus providing a hybrid model for efficient quantum information processing. In this work we develop validity conditions for [...]
