Certification and Quantification of Multilevel Quantum Coherence

2018 · Physical Review X

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within a resource-theoretic …

Towards experimental classical verification of quantum computation

2024 · Quantum Science and Technology

Abstract With today’s quantum processors venturing into regimes beyond the capabilities of classical devices, we face the challenge to verify that these devices perform as intended, even when we cannot check their results on classical …

A universal qudit quantum processor with trapped ions

2021 · arXiv (Cornell University)

Today's quantum computers operate with a binary encoding that is the quantum analog of classical bits. Yet, the underlying quantum hardware consists of information carriers that are not necessarily binary, but typically exhibit a rich …
