Maximization of Extractable Randomness in a Quantum Random-Number Generator
Jing Yan Haw,Syed M. Assad,Andrew M. Lance,Nelly Huei Ying Ng,V. Sharma,Ping Koy Lam,Thomas Symul +6 more
TL;DR: In this article, a method for maximizing the conditional min-entropy of the number sequence generated from a given quantum-to-classical noise ratio is presented, which can achieve real-time random number generation rate of 14 (Mbit/s)/MHz.
Journal ArticleDOI
Min-entropy uncertainty relation for finite-size cryptography.
TL;DR: A new uncertainty relation is proved in terms of the smooth min-entropy that is only marginally less strong, but has the crucial property that it can be applied to rather small block lengths, which paves the way for a practical implementation of many cryptographic protocols.
Journal ArticleDOI
Surpassing the Carnot efficiency by extracting imperfect work
Nelly Huei Ying Ng,Nelly Huei Ying Ng,Mischa P. Woods,Mischa P. Woods,Stephanie Wehner,Stephanie Wehner +5 more
TL;DR: It is shown that the definition of "work" is crucial and if one allows for a definition of work that tolerates a non-negligible entropy increase in the battery, then a small scale heat engine can possibly exceed the Carnot efficiency.
Journal ArticleDOI
Quantum field thermal machines
Marek Gluza,João Sabino,João Sabino,Nelly Huei Ying Ng,Nelly Huei Ying Ng,Giuseppe Vitagliano,Marco Pezzutto,Yasser Omar,Igor Mazets,Igor Mazets,Marcus Huber,Marcus Huber,Jörg Schmiedmayer,Jens Eisert +13 more
TL;DR: A blueprint of quantum field machines, which - once experimentally realized - would fill the gap in the lack of experimental implementations of thermal machines in which quantum effects play a decisive role, is introduced.
Journal ArticleDOI
Smoothed generalized free energies for thermodynamics
TL;DR: In this paper, the authors introduced a family of smoothed generalized free energies, by constructing explicit smoothing procedures that maximize or minimize the free energy over an $\ensuremath{\varepsilon}$ ball of quantum states.
