Classical and Quantum Information Transmission and Interactionst also of intact quantum states. We survey known upper and lower bounds on the capacity of quantum channels, alone or assisted by one- or two-way classical communication, to transmit intact quantum states, and relation of this capacity on the one hand to classical capacity and on the other to the qu

Bounds of the Accessible Information under the Influence of Thermal Noiseerived by means of the superoperator representation of quantum states. It is shown that the upper bound is obtained by replacing the parameters of the Gaussian quantum state with the renormalized parameters including the thermal noise effect in the accessible information in the absence of thermal no

Optimum Binary Signal Detections for Error Probability and Mutual Informationo implement super-reliable communication systems, quantum computers, etc [1–6]. The optimum detection operators which are the mathematical description of the optimum signal detection process have been derived for some signal quantum states in the case of the error probability [7, 8]. However, in the

Entanglement-Enhanced Classical Communication on a Noisy Quantum Channelor a quantum channel, the possibility exists of entangling the channel inputs, which of course cannot be done with a classical channel. We show that, for certain noisy quantum channels, such entangled transmissions increase the receiver’s probability of a correct inference, above what can be achieve

Security Against Eavesdropping in Quantum Cryptographylassical cryptography. For more reviews of this topic see [1–3]. Bennett and Brassard showed that it is possible, at least ideally, to create a secret key, shared by sender and receiver, without both parties sharing any secret beforehand. We refer to this protocol as the . protocol [4]. To achieve t
