Dynamic Programming for Quantum Circuit Optimization with Uncertainty
Jincheng Zhang
Abstract
Quantum circuit optimization is a crucial step in realizing the full potential of quantum computing. However, the inherent uncertainty in quantum gate fidelities and measurement outcomes presents a significant challenge. Traditional optimization methods often fail to adequately address this probabilistic nature. This paper proposes a novel dynamic programming approach for quantum circuit optimization that explicitly incorporates uncertainty. The algorithm constructs an optimal circuit path by minimizing the expected cost, which accounts for the potential error associated with each gate operation and measurement. This framework allows for a more accurate and robust optimization process, leading to circuits with reduced error and improved performance. The core claim is that dynamic programming can be effectively applied to quantum circuit optimization, acknowledging and utilizing the probabilistic elements. The key mechanism involves a structured, iterative process to evaluate and select the best circuit paths based on a quantified uncertainty model. This approach avoids the limitations of purely deterministic optimization techniques when dealing with quantum systems.
