Two-Way Quantum Communication: ‘Secure Quantum Information Exchange’-II. Generalization to Arbitrary Number of Qubits

In this paper, we generalize the secure quantum information exchange (SQIE) protocol, originally proposed by the authors [J. Phys. B: At. Mol. Opt. Phys. 44 (2011) 115504] for secure exchange of one qubit information with each of Alice and Bob, to the case of secure exchange of quantum information of arbitrary qubits with Alice and Bob. We also discuss security of the original and generalized S...

Bisimulation is Two-Way Simulation

We give here a simple proof of the fact that on transition systems bisimulation is the equivalence relation generated by simulation via functions. The proof entirely rests on simple rules of the calculus of relations. Simulation is a standard notion of graph homomor-phism that has been used in the study of flow diagram programs (see, e.g. [ 6,7,11]). Bisimulationis an equivalence on transition ...

Two-way Channel In Information Theory

Firstly, an introduction of two-way communications channel is given. Then Shannon’s inner and outer bounds are introduced. Upon Shannon’s bounds, tighter lower and upper bounds are found for general discrete memoryless two-way channels. After that, the capacity regions of some specific two-way channels are discussed. Finally, a summary is given.
