On complementary channels and the additivity problem
We explore complementarity between output and environment of a quantum channel (or, more generally, CP map), making an observation that the output purity characteristics for complementary CP maps coincide. Hence, validity of the mutiplicativity/additivity conjecture for a class of CP maps implies its validity for complementary maps. The class of CP maps complementary to entanglement-breaking on...
متن کاملThe Additivity Problem for Data
Functional dependencies (FDs) and inclusion dependencies (INDs) are the most fundamental integrity constraints that arise in practice in relational databases. We introduce null functional dependencies (NFDs) and null inclusion dependencies (NINDs) to cater for the situation when a database is incomplete and thus contains null values. If a NFD or NIND is weakly satissed in a database, then there...
متن کاملAdditivity for Unital Qubit Channels
Additivity of the Holevo capacity is proved for product channels, under the condition that one of the channels is a unital qubit channel, with the other completely arbitrary. As a byproduct this proves that the Holevo bound is the ultimate information capacity of such qubit channels (assuming no prior entanglement between sender and receiver). Additivity of minimal entropy and multiplicativity ...
متن کاملComplementarity and additivity for depolarizing channels
In this paper we use the method of the paper [10] to compute complementary channels for certain important cases, such as depolarizing and transpose-depolarizing channels. This method allows us to easily obtain the minimal Kraus representations from non–minimal ones. We also study the properties of the output purity of the tensor product of a channel and its complement.
متن کاملAdditivity and Distinguishability of Random Unitary Channels
A random unitary channel is one that is given by a convex combination of unitary channels. It is shown that the conjectures on the additivity of the minimum output entropy and the multiplicativity of the maximum output p-norm can be equivalently restated in terms of random unitary channels. This is done by constructing a random unitary approximation to a general quantum channel. This approximat...
