Partitioned-Constraint QAOA (PC-QAOA): Structural State Preparation and Penalty Enforcement for Quantum Optimization
Anthony Wilkie, Alexander DeLise, Andrew Del Real +2
Constrained combinatorial optimization remains challenging for quantum algorithms because feasibility must be explicitly enforced, typically through penalty terms or problem-specif…
Explicit Block Encoding of Difference-of-Gaussian Operators on a Periodic Grid
Jishnu Mahmud, John Winship, Tom Lash +2
The Difference-of-Gaussian (DoG) is a widely used operator across applications, including image processing (feature and edge detection), quantum machine learning, and finite-differ…
A mixed-integer program for circuit execution time minimization with precedence constraints
Mostafa Atallah, James Ostrowski, Rebekah Herrman
We present a mixed-integer programming (MIP) model for scheduling quantum circuits to minimize execution time. Our approach maximizes parallelism by allowing non-overlapping gates…
Quantum approximate optimization algorithm with random and subgraph phase operators
Anthony Wilkie, Igor Gaidai, James Ostrowski +1
The quantum approximate optimization algorithm (QAOA) is a promising quantum algorithm that can be used to approximately solve combinatorial optimization problems. The usual QAOA a…
