Sequential, successive, and simultaneous decoders for entanglement-assisted classical communication
simultaneous decoders entanglement-assisted classical communication Quantum Physics
2011/9/29
Abstract: Bennett et al. showed that allowing shared entanglement between a sender and receiver before communication begins dramatically simplifies the theory of quantum channels, and these results su...
Quantum One-Way Communication is Exponentially Stronger Than Classical Communication
Quantum One-Way Communication Classical Communication
2010/10/27
In STOC 1999, Raz presented a (partial) function for which there is a quantum protocol
communicating only O(log n) qubits, but for which any classical (randomized, bounded-error)
protocol requires p...
Quantum phase with no translational symmetry and its potentiality for quantum communication
Quantum phase symmetry quantum communication
2010/4/16
By the method of terahertz photo-voltaic spectroscopy we have found a quantum phase that possesses neither continuous nor discrete translational symmetry. The phase is originated from quantum Hall sta...
The role of chaos in quantum communication through a dynamical dephasing channel
quantum communication dynamical dephasing channel
2010/4/6
In this article we treat the subject of chaotic environments with few degrees of freedom in quantum communication by investigating a conservative dynamical map as a model of a dephasing quantum channe...
Communicating with nuclear-powered submarines – which can remain underwater essentially indefinitely – is a major challenge because seawater is opaque to most of the electromagnetic spectrum. Neutrino...
Quantum Teamwork for Unconditional Multiparty Communication with Gaussian States
Quantum Teamwork Unconditional Multiparty Communication Gaussian States
2010/4/8
We demonstrate the capability of continuous variable Gaussian states to communicate multipartite quantum information. A quantum teamwork protocol is presented according to which an arbitrary possibly ...
Non-locality distillation and post-quantum theories with trivial communication complexity
Non-locality distillation post-quantum theories trivial communication complexity
2010/4/9
We first present a protocol for deterministically distilling non-locality, building upon a recent result of Forster et al. [Phys. Rev. Lett. 102, 120401 (2009)]. Our protocol, which is optimal for two...
Trading classical communication, quantum communication, and entanglement in quantum Shannon theory
Trading classical communication quantum communication quantum Shannon theory
2010/4/9
We give optimal trade-offs between classical communication, quantum communication, and entanglement for processing information in the Shannon-theoretic setting. We first prove a "unit-resource" capaci...
