The private classical information capacity and quantum information capacity of a quantum channel
A formula for the capacity of a quantum channel for transmitting private classical information is derived. This is shown to be equal to the capacity of the channel for generating a secret key, and neither capacity is enhanced by forward public classical communication. Motivated by the work of Schumacher and Westmoreland on quantum privacy and quantum coherence, parallels between private classic...
متن کاملClassical information capacity of a quantum channel.
We consider the transmission of classical information over a quantum channel. The channel is deened by an \alphabet" of quantum states, e.g. certain photon polarizations, together with a speciied set of probabilities with which these states must be sent. The Levitin-Kholevo theorem implies that the amount of information transmitted per \letter" cannot be greater than the von Neumann entropy H o...
متن کاملInformation capacity formula of quantum optical channels
The applications of the general formulae of channel capacity developed in the quantum information theory to evaluation of information transmission capacity of optical channel are interesting subjects. In this review paper, we will point out that the formulation based on only classicalquantum channel mapping model may be inadequate when one takes into account a power constraint for noisy channel...
متن کاملMeasuring Observable Quantum Contextuality
Contextuality is a central property in comparative analysis of classical, quantum, and supercorrelated systems. We examine and compare two well-motivated approaches to contextuality. One approach (“contextuality-by-default”) is based on the idea that one and the same physical property measured under different conditions (contexts) is represented by different random variables. The other approach...
متن کاملOn Entangled Information and Quantum Capacity
The pure quantum entanglement is generalized to the case of mixed compound states on an operator algebra to include the classical and quantum encodings as particular cases. The true quantum entanglements are characterized by quantum couplings which are described as transpose-CP, but not Completely Positive (CP), trace-normalized linear positive maps of the algebra. The entangled (total) informa...
