Classical data compression with quantum side information
The problem of classical data compression when the decoder has quantum side information at his disposal is considered. This is a quantum generalization of the classical Slepian-Wolf theorem. The optimal compression rate is found to be H(X)−χ where H(X) is the Shannon entropy of the source and χ is the Holevo quantity of the ensemble describing the classicalquantum correlations between the sourc...
متن کاملState-dependent Networks with Side Information and Partial State Recovery
by Shiva Prasad Kotagiri In many communication scenarios, the communicating parties typically have some knowledge or attempt to learn about the time-varying environment or the channel over which communication takes place. To understand these models, it is important to study the fundamental performance limits of state-dependent channels whose probabilistic input-output relationship depends on a ...
متن کاملBounds on Information Combining With Quantum Side Information
Bounds on information combining” are entropic inequalities that determine how the information (entropy) of a set of random variables can change when these are combined in certain prescribed ways. Such bounds play an important role in classical information theory, particularly in coding and Shannon theory; entropy power inequalities are special instances of them. The arguably most elementary kin...
متن کاملCoding for quantum channels with side information at the transmitter
We consider the problem of coding for quantum channels with side information that is available ahead of time at the transmitter but not at the receiver. We find a single-letter expression for the entanglement-assisted quantum capacity of such channels which closely parallels Gel’fand and Pinsker’s solution to the classical version of the same problem. This theorem can also be used to find a low...
متن کاملMeasurement compression with quantum side information using shared randomness
We consider the problem of measurement compression with side information in the one-shot setting with shared randomness. In this problem, Alice shares a pure state with Referee and Bob and she performs a measurement on her registers. She wishes to communicate the outcome of this measurement to Bob using shared randomness only, in such a way that the outcome that Bob receives is correctly correl...
