Collective Operations Can Exponentially Enhance Quantum State Verification

2022 · Physical Review Letters

Maximally entangled states are a key resource in many quantum communication and computation tasks, and their certification is a crucial element to guarantee the desired functionality. We introduce collective strategies for the efficient, local verification …

Enhancing Quantum Computation via Superposition of Quantum Gates

2023 · arXiv (Cornell University)

Overcoming the influence of noise and imperfections in quantum devices is one of the main challenges for viable quantum applications. In this article, we present different protocols, which we denote as "superposed quantum error mitigation", …
