Upper bounds for relative entropy of entanglement based on convex hull approximation
2019 · arXiv (Cornell University)
Quantifying entanglement for multipartite quantum state is a crucial task in many aspects of quantum information theory. Among all the entanglement measures, relative entropy of entanglement $E_{R}$ is an important quantity due to its clear …

Learning quantum phases via single-qubit disentanglement
2021 · arXiv (Cornell University)
Identifying phases of matter presents considerable challenges, particularly within the domain of quantum theory, where the complexity of ground states appears to increase exponentially with system size. Quantum many-body systems exhibit an array of complex …

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 …
