Entanglement-Enhanced Classical Communication on a Noisy Quantum Channel
We consider the problem of trying to send a single classical bit through a noisy quantum channel when two transmissions through the channel are available as a resource. Classically, two transmissions add nothing to the receiver’s capability of inferring the bit. In the quantum world, however, one has the possible further advantage of entangling the two transmissions. We demonstrate that, for ce...
متن کاملEntanglement enhancement of a noisy classical communication channel
Abstract We present a formal quantum mechanical analysis of the communication protocol of Prevedel et al. [Phys. Rev. Lett. 106, 110505 (2011)], in which entanglement shared by sender and receiver is used to enhance, beyond that achievable via the optimal classical strategy, the probability of successful transmission of a bit through a particular noisy classical channel N . We provide a full an...
متن کاملQuantum entanglement and classical communication through a depolarising channel
We analyse the role of entanglement for transmission of classical information through a memoryless depolarising channel. Using the isotropic character of this channel we prove analytically that the mutual information cannot be increased by encoding classical bits into entangled states of two qubits.
متن کاملEntanglement can increase asymptotic rates of zero-error classical communication over classical channels
It is known that the number of different classical messages which can be communicated with a single use of a classical channel with zero probability of decoding error can sometimes be increased by using entanglement shared between sender and receiver. It has been an open question to determine whether entanglement can ever offer an advantage in terms of the zero-error communication rates achieva...
متن کاملOptimal entanglement-assisted one-shot classical communication
The one-shot success probability of a noisy classical channel for transmitting one classical bit is the optimal probability with which the bit can be successfully sent via a single use of the channel. Prevedel et al. [Phys. Rev. Lett. 106, 110505 (2011)] recently showed that for a specific channel, this quantity can be increased if the parties using the channel share an entangled quantum state....
