Towards symmetric scheme for superdense coding between multiparties
Recently Liu, Long, Tong and Li [Phys. Rev. A 65, 022304 (2002)] have proposed a scheme for superdense coding between multiparties. This scheme seems to be highly asymmetric in the sense that only one sender effectively exploits entanglement. We show that this scheme can be modified in order to allow more senders to benefit of the entanglement enhanced information transmission. PACS number(s): ...
متن کاملQuantum Teleportation between Multiparties
The paper presents general protocols for quantum teleportation between multiparties. It is shown how N parties can teleport N unknown quantum states to M other parties with the use of M N + qudits in the maximally entangled state. It is also shown that a single pair of qudits in the maximally entangled state can be used to teleport two qudits in opposite directions simultaneously. PACS number(s...
متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...
متن کاملEntanglement Witness Derived From NMR Superdense Coding
We show that it is possible to transfer two-bit information via encoding a single qubit in a conventional nuclear magnetic resonance (NMR) experiment with two very weakly polarized nuclear spins. Nevertheless, the experiment can not be regarded as a demonstration of superdense coding by means of NMR because it is based on the large number of molecules being involved in the ensemble state rather...
متن کاملLeakage Chain Rule and Superdense Coding
In this note, we reprove the communication lower bound of Holevo’s problem, using the Leakage Chain Rule for quantum min-entropy.
