An entanglement perspective on the quantum approximate optimization algorithm

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicolas Didier, Mark J. Hodson, Joel E. Moore, Matthew J. Reagor | Summary: Many quantum algorithms seek to output a specific bitstring solving the problem of interest–or a few if the solution is degenerate. It is the case for the quantum approximate optimization algorithm […]

Calibrating the classical hardness of the quantum approximate optimization algorithm

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicolas Didier, Mark J. Hodson, Joel E. Moore, Matthew J. Reagor | Summary: Trading fidelity for scale enables approximate classical simulators such as matrix product states (MPS) to run quantum circuits beyond exact methods. A control parameter, the so-called bond dimension $chi$ for MPS, […]
