One-shot coherence distillation with catalysts

Senrui Chen, Xingjian Zhang, You Zhou, Qi Zhao
2019 Physical Review A  
In order to distill more coherence from a state of interest, a catalytic system can be involved and a jointly free operation is applied to both systems.  ...  Firstly, with a small fidelity error in both systems, we show that, even via the smallest free operation class (PIO), the distillable coherence of any state with no restriction on the catalysts is infinite  ...  Let H A , H C denote the Hilbert spaces of the system of interest and the catalytic system, respectively.  ...

Purely Catalytic P Systems over Integers and Their Generative Power [chapter]

2017 Lecture Notes in Computer Science  
We further investigate the computing power of the recently introduced P systems with Z-multisets (also known as hybrid sets) as generative devices.  ...  These systems apply catalytic rules in the maximally parallel way, even consuming absent non-catalysts, thus effectively generating vectors of arbitrary (not just non-negative) integers.  ...  Purely Catalytic P Systems over Integers In purely catalytic P systems over integers the set of objects is a disjoint union of catalysts C and the regular objects O.  ...

Catalysis of entanglement and other quantum resources [article]

Chandan Datta, Tulja Varun Kondra, Marek Miller, Alexander Streltsov
2022 arXiv   pre-print
Catalytic embezzling is also considered, a phenomenon which occurs if the state of the catalyst can change in the transition.  ...  We review applications of quantum catalysis, and discuss also the recent efforts on universal catalysis, where the quantum state of the catalyst does not depend on the states to be transformed.  ...  In this sense, one can speak of a universal catalytic state for pure-state entanglement.  ...

Catalytic coherence transformations

Kaifeng Bu, Uttam Singh, Junde Wu
2016 Physical Review A  
Here we find the necessary and sufficient conditions for the deterministic and stochastic catalytic coherence transformations between pair of pure quantum states.  ...  Catalytic coherence transformations allow the otherwise impossible state transformations using only incoherent operations with the aid of an auxiliary system with finite coherence which is not being consumed  ...  -The possibility of transformation of a quantum system from one state with finite coherence to another state is determined by the majorization of the diagonal elements of the corresponding pure states  ...
