Catalytic quantum randomness as a correlational resource
نویسندگان
چکیده
Catalysts are substances that assist transformation of other resourceful objects without being consumed in the process. However, fact their ``catalytic power'' is limited and can be depleted often overlooked, especially recently developing theories on catalysis quantum randomness utilizing building correlation with catalyst. In this work, we establish a resource theory one-shot catalytic which uncorrelatedness randomness. We do so by completely characterizing bipartite unitary operators used to implement using partial transpose. By doing so, find every channel factorizable, therefore there exists unital not catalytic. define family entropies quantifies catalytically extractable R\'enyi from state show how much degeneracy boost entropy beyond its ordinary entropy. Based this, demonstrate source actually exhausted after certain amount extracted. apply systems under superselection rules forbids superposition states nonmaximally mixed yield maximal discuss implications various topics, including absorption, no-secret theorem, possibility multiparty infinite catalysis.

متن کاملThe probability distribution as a computational resource for randomness testing
When testing a set of data for randomness according to a probability distribution that depends on a parameter, access to this parameter can be considered as a computational resource. We call a randomness test Hippocratic if it is not permitted to access this resource. In these terms, we show that for Bernoulli measures μp, 0 6 p 6 1 and the Martin-Löf randomness model, Hippocratic randomness of...
متن کاملA Global Equilibrium as the Foundation of Quantum Randomness
We analyze the origin of quantum randomness within the framework of a completely deterministic theory of particle motion—Bohmian mechanics. We show that a universe governed by this mechanics evolves in such a way as to give rise to the appearance of randomness, with empirical distributions in agreement with the predictions of the quantum formalism. Crucial ingredients in our analysis are the co...
متن کاملQuantum entanglement as a quantifiable resource
Quantum mechanical objects can exhibit correlations with one another that are fundamentally at odds with the paradigm of classical physics; one says that the objects are ‘entangled’. In the past few years, entanglement has come to be studied not only as a marvel of nature but as a potential resource, particularly as a resource for certain unusual kinds of communication. This paper reviews two s...
متن کاملQuantum discord as a resource for quantum cryptography
Quantum discord is the minimal bipartite resource which is needed for a secure quantum key distribution, being a cryptographic primitive equivalent to non-orthogonality. Its role becomes crucial in device-dependent quantum cryptography, where the presence of preparation and detection noise (inaccessible to all parties) may be so strong to prevent the distribution and distillation of entanglemen...
