Quantum Speed Limit for Change of Basis
Moein Naseri, Chiara Macchiavello, Dagmar Bruß +2
Quantum speed limits provide ultimate bounds on the time required to transform one quantum state into another. Here, we extend the notion of quantum speed limits to collections of…
Upper bound on the Guessing probability using Machine Learning
Sarnava Datta, Hermann Kampermann, Dagmar Bruß
The estimation of the guessing probability has paramount importance in quantum cryptographic processes. It can also be used as a witness for nonlocal correlations. In most of the s…
Continuity of robustness measures in quantum resource theories
Jonathan Schluck, Gláucia Murta, Hermann Kampermann +2
Robustness measures are increasingly prominent resource quantifiers that have been introduced for quantum resource theories such as entanglement and coherence. Despite the generali…
Construction of efficient Schmidt number witnesses for high-dimensional quantum states
Nikolai Wyderka, Giovanni Chesi, Hermann Kampermann +2
Recent progress in quantum optics has led to setups that are able to prepare high-dimensional quantum states for quantum information processing tasks. As such, it is of importance…
Boosting device-independent cryptography with tripartite nonlocality
Federico Grasselli, Gláucia Murta, Hermann Kampermann +1
Device-independent (DI) protocols, such as DI conference key agreement (DICKA) and DI randomness expansion (DIRE), certify private randomness by observing nonlocal correlations whe…
Learning logical Pauli noise in quantum error correction
Thomas Wagner, Hermann Kampermann, Dagmar Bruß +1
The characterization of quantum devices is crucial for their practical implementation but can be costly in experimental effort and classical postprocessing. Therefore, it is desira…
