Mitigating algorithmic errors in quantum optimization through energy extrapolation

2022 · Quantum Science and Technology

Abstract Quantum optimization algorithms offer a promising route to finding the ground states of target Hamiltonians on near-term quantum devices. Nonetheless, it remains necessary to limit the evolution time and circuit depth as much as …

Tapping into Permutation Symmetry for Improved Detection of k-Symmetric Extensions

2023 · Entropy

Symmetric extensions are essential in quantum mechanics, providing a lens through which to investigate the correlations of entangled quantum systems and to address challenges like the quantum marginal problem. Though semi-definite programming (SDP) is a …
