On converse bounds for classical communication over quantum channels

We explore several new converse bounds for classical communication over quantum channels in both the one-shot and asymptotic regime. First, we show that the MatthewsWehner meta-converse bound for entanglement-assisted classical communication can be achieved by activated, no-signalling assisted codes, suitably generalizing a result for classical channels. Second, we derive a new efficiently comp...

New bounds on classical and quantum one-way communication complexity

In this paper we provide new bounds on classical and quantum distributional communication complexity in the two-party, one-way model of communication. In the classical one-way model, our bound extends the well known upper bound of Kremer, Nisan and Ron [KNR95] to include non-product distributions. Let ǫ ∈ (0, 1/2) be a constant. We show that for a boolean function f : X ×Y → {0, 1} and a non-pr...

Strong converse for identification via quantum channels

In this paper we present a simple proof of the strong converse for identification via discrete memoryless quantum channels, based on a novel covering lemma. The new method is a generalization to quantum communication channels of Ahlswede’s recently discovered appoach to classical channels. It involves a development of explicit large deviation estimates to the case of random variables taking val...

State Dependent Channels: Strong Converse and Bounds on Reliability Function

We consider an information theoretic model of a communication channel with a time-varying probability law. Specifically, our model consists of a state dependent discrete memoryless channel, in which the underlying state process is independent and identically distributed with known probability distribution, and for which the channel output at any time instant depends on the inputs and states onl...

Error Bounds for Digital Communication over Spatially Modulated Channels

The transmission of digital information by means of electromagnetic wave propagation between terminals is reconsidered in order to understand the influence of the radiation channel, including the terminal antennas, on the quality of communication that can be maintained. In particular, we investigate the potential to improve performance by modulating the messages onto a set of spatially varying ...
