Polynomial scaling of QAOA for ground-state preparation: taming first-order phase transitions

2020 · arXiv (Cornell University)

We show that the quantum approximate optimization algorithm (QAOA) can construct with polynomially scaling resources the ground state of the fully-connected p-spin Ising ferromagnet, a problem that notoriously poses severe difficulties to a Quantum Annealing …

Error Mitigation for Quantum Approximate Optimization

2023 · arXiv (Cornell University)

Solving optimization problems on near term quantum devices requires developing error mitigation techniques to cope with hardware decoherence and dephasing processes. We propose a mitigation technique based on the LHZ architecture. This architecture uses a …
