A computer-implemented method to generate quantum algorithms

Abstract

The invention pertains to a method for providing a digital quantum algorithm comprising the steps of: a) Providing an analog adiabatic quantum algorithm that includes a Hamiltonian function (Hamiltonian Operator) that solves a given problem, b) Adding at least one approximated counterdiabatic (CD) term to the Hamiltonian function of the analog quantum algorithm to obtain a counterdiabatic-enhanced (CD) adiabatic quantum algorithm, and c) Digitizing the counterdiabatic-enhanced adiabatic quantum algorithm from step b) to obtain a digital quantum algorithm. The invention leads to a reduction in the number of qubits, quantum gates, and operations needed on a noisy intermediate scale quantum (NISQ) computer with digital and analog hardware.
