Nonadiabatic Self-Healing of Trotter Errors in Digitized Counterdiabatic Dynamics
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +3
Trotter errors in digitized quantum dynamics arise from approximating time-ordered evolution under noncommuting Hamiltonian terms with a product formula. In the adiabatic regime, s…

Convergence of Digitized-Counterdiabatic QAOA: circuit depth versus free parameters
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +1
Recently, Digitized-Counterdiabatic (CD) Quantum Approximate Optimization Algorithm (QAOA) has been proposed to make QAOA converge to the solution of an optimization problem in few…
