arXiv:2606.23718v1 Announce Type: cross Abstract: The Quantum Approximate Optimization Algorithm (QAOA) is a leading variational algorithm for combinatorial optimization on near term quantum devices. As circuit depth increases, the number of optimization parameters grows, making the search landscape increasingly nonlinear and difficult to optimize. Previous studies have shown that optimal QAOA parameters often lie on a low dimensional manifold that can be approximated using Principal Component Analysis (PCA) at shallow circuit depths. However, the effectiveness of PCA decreases at higher depth
The continuous drive to improve the efficiency and applicability of quantum algorithms on near-term quantum devices necessitates novel optimization techniques.
This research could significantly advance the practical viability of Quantum Approximate Optimization Algorithms (QAOA) by addressing a critical scaling limitation, potentially accelerating quantum computing applications in optimization.
The ability to reduce the dimensionality of QAOA parameter spaces means more complex combinatorial optimization problems might become tractable sooner on current or near-term quantum hardware.
