Native qudit entanglement in a trapped ion quantum processor
Pavel Hrmo, Benjamin Wilhelm, Lukas Gerster +6
Quantum information carriers, just like most physical systems, naturally occupy high-dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high-dim…
Versatile fidelity estimation with confidence
Akshay Seshadri, Martin Ringbauer, Jacob Spainhour +3
As quantum devices become more complex and the requirements on these devices become more demanding, it is crucial to be able to verify the performance of such devices in a scalable…
Probing the Non-Classicality of Temporal Correlations
Martin Ringbauer, Rafael Chaves
Correlations between spacelike separated measurements on entangled quantum systems are stronger than any classical correlations and are at the heart of numerous quantum technologie…
Quantum discord as resource for remote state preparation
Borivoje Dakic, Yannick Ole Lipp, Xiaosong Ma +8
Quantum entanglement is widely recognized as one of the key resources for the advantages of quantum information processing, including universal quantum computation, reduction of co…
Experimental measurement and a physical interpretation of quantum shadow enumerators
Daniel Miller, Kyano Levi, Lukas Postler +18
Throughout its history, the theory of quantum error correction has heavily benefited from translating classical concepts into the quantum setting. In particular, classical notions…
Characterizing quantum dynamics with initial system-environment correlations
Martin Ringbauer, Christopher J. Wood, Kavan Modi +3
We fully characterize the reduced dynamics of an open quantum system initially correlated with its environment. Using a photonic qubit coupled to a simulated environment we tomogra…
