Enhancing NDAR with Delay-Gate-Induced Amplitude Damping

Understand

The Noise-Directed Adaptive Remapping (NDAR) method utilizes amplitude damping noise to enhance the performance of quantum optimization algorithms.

• NDAR alternates between exploration by sampling solutions from the quantum circuit and exploitation by transforming the cost Hamiltonian by changing the signs of its terms.
• Both exploration and exploitation are important components in classical heuristic algorithm design.
• In this study, we examine how NDAR performance improves by adjusting the balance between these components.
