Information transmission through a noisy quantum channel
Noisy quantum channels may be used in many information-carrying applications. We show that different applications may result in different channel capacities. Upper bounds on several of these capacities are proved. These bounds are based on the coherent information, which plays a role in quantum information theory analogous to that played by the mutual information in classical information theory...
متن کاملEntanglement between two uses of a noisy multipartite quantum channel enables perfect transmission of classical information.
Suppose that m senders want to transmit classical information to n receivers with zero probability of error using a noisy multipartite communication channel. The senders are allowed to exchange classical, but not quantum, messages among themselves, and the same holds for the receivers. If the channel is classical, a single use can transmit information if and only if multiple uses can. In sharp ...
متن کاملQuantum bit commitment in a noisy channel
Under rather general assumptions about the properties of a noisy quantum channel, a first quantum protocol is proposed which allows to implement the secret bit commitment with the probability arbitrarily close to unity. The idea that quantum physics can provide more secure communication between two distant parties than the classical one was first put forward by Wiesner [1]. Later, after the wor...
متن کاملInformation Processing by a Noisy Binary Channel
We study the information processing properties of a binary channel receiving data from a gaussian source. A systematic comparison with linear processing is done. A remarkable property of the binary sytem is that, as the ratio between the number of output and input units increases, binary processing becomes equivalent to linear processing with a quantization output noise that depends on. In this...
متن کاملEfficient Quantum Information Transfer Through a Uniform Channel
Effective quantum‐state and entanglement transfer can be obtained by inducing a coherent dynamics in quantum wires with homogeneous intrawire interactions. This goal is accomplished by optimally tuning the coupling between the wire endpoints and the two qubits there attached. A general procedure to determine such value is devised, and scaling laws between the optima...
