Certified Randomness Generation against Quantum Adversaries via Energy Constraints
Thomas A. Hahn, Efrat Gerchkovitz, Ester Yehuda +1
For quantum random number generators (QRNGs), strong security guarantees can be obtained under various assumptions. The most well-known assumptions are the non-signalling assumptio…
Accessible Quantum Correlations Under Complexity Constraints
Álvaro Yángüez, Noam Avidan, Jan Kochanowski +1
Quantum systems may contain underlying correlations which are inaccessible to computationally bounded observers. We capture this distinction through a framework that analyses bipar…
Efficient Quantum Measurements: Computational Max- and Measured Rényi Divergences and Applications
Álvaro Yángüez, Thomas A. Hahn, Jan Kochanowski
Quantum information processing is limited, in practice, to efficiently implementable operations. This motivates the study of quantum divergences that preserve their operational mea…
Fully Quantum Computational Entropies
Noam Avidan, Thomas A. Hahn, Joseph M. Renes +1
Quantum information theory, particularly its entropic formulations, has made remarkable strides in characterizing quantum systems and tasks. However, a critical dimension remains u…
