Non-Directional Property of Human–Body Communication Channel for Implantable Device Application
Sensors, 2023 In this paper, we present the properties of a communication channel used for implantable devices. The human–body communication (HBC) channel was proposed for data communication in implantable devices.

Top Quark Production Measurements at ATLAS
, 2011 An overview of top quark production measurements using the ATLAS detector at the LHC is presented. Using 35 pb^-1 of data, we measured the ttbar cross-section in the lepton+jets channel to 13% precision and set limits on the cross-section for the all ...

Quantum communication via a continuously monitored dual spin chain
, 2007 We analyze a recent protocol for the transmission of quantum states via a dual spin chain [Burgarth and Bose, Phys. Rev. A 71, 052315 (2005)] under the constraint that the receiver's measurement strength is finite.

Dynamic measurements for funny channels [PDF]
Proceedings of the National Academy of Sciences, 2014 Proteins possess the uncanny ability to telegraph signals over long distances. The presence of a ligand, snugly bound to a site on one end of a molecule, can be “felt” by an effector domain several nanometers away. Determining precisely how this task is accomplished is a major challenge for structural biologists.

Quantum Gaussian channels with weak measurements
Quantum Information and Computation, 2015 In this paper we perform a novel analysis of quantum Gaussian channels in the context of weak measurements. Suppose Alice sends classical information to Bob using a quantum channel. Suppose Bob is allowed to use only weak measurements, what would be the channel capacity? We formulate weak measurement theory in these terms and discuss the above question.

On wireless channel modelling : extraction of channel from channel measurements [PDF]
2007 International Symposium on Communications and Information Technologies, 2007 Next generation systems are using directional antennas for indoor high data rate devices. This arises a need for measurement and modelling of directional channels. Indoor environments also introduce extreme multipath behaviour into the directional channel.

Research on reflection characteristics of the terahertz channel for 6G
Tongxin xuebao, 2022 The reflection characteristics of the terahertz channel are crucial for understanding and mastering the propagation mechanism of the terahertz channel, which are also required for a high-precision terahertz channel model for 6G.Therefore, the research ...

, 2016 Based on the quantum technique of weak measurement, we propose a scheme to protect the entanglement from correlated amplitude damping decoherence. In contrast to the results of memoryless amplitude damping channel, we show that the memory effects play a ...

Approximate reversibility in the context of entropy gain, information gain, and complete positivity [PDF]
, 2016 There are several inequalities in physics which limit how well we can process physical systems to achieve some intended goal, including the second law of thermodynamics, entropy bounds in quantum information theory, and the uncertainty principle of ...
