Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Optimization and synchronization of programmable quantum communication channels
, 2018 Quantum applications transmit and receive data through quantum and classical communication channels. Channel capacity, the distance and the photon path between transmitting and receiving parties and the speed of the computation links play an essential ...

Moderate Deviation Analysis for Classical-Quantum Channels and Quantum Hypothesis Testing [PDF]
IEEE Transactions on Information Theory, 2017 In this paper, we study the tradeoffs between the error probabilities of classical-quantum channels and the blocklength $n$ when the transmission rates approach the channel capacity at a rate lower than $1/\sqrt {n}$ , a research topic known as ...

Dequantization Via Quantum Channels [PDF]
Letters in Mathematical Physics, 2016 For a unital completely positive map $ $ ("quantum channel") governing the time propagation of a quantum system, the Stinespring representation gives an enlarged system evolving unitarily. We argue that the Stinespring representations of each power $ ^m$ of the single map together encode the structure of the original quantum channel and provides an ...

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Experimental demonstration of a measurement-based realisation of a quantum channel
New Journal of Physics, 2018 We introduce and experimentally demonstrate a method for realising a quantum channel using the measurement-based model. Using a photonic setup and modifying the basis of single-qubit measurements on a four-qubit entangled cluster state, representative ...

Quantum-correlation breaking channels, quantum conditional probability and Perron-Frobenius theory
, 2013 Using the quantum analog of conditional probability and classical Bayes theorem we discuss some aspects of quantum-classical and classical-classical channels in connection to the recent paper J. Korbicz, P. Horodecki, and R.

Applications of position-based coding to classical communication over quantum channels [PDF]
Information Theory Workshop, 2017 Recently, a coding technique called position-based coding has been used to establish achievability statements for various kinds of classical communication protocols that use quantum channels.

Factorizations of quantum channels [PDF]
Linear Algebra and its Applications, 2018 We find a connection between the existence of a factorization of a quantum channel and the existence of low-rank solutions to certain linear matrix equations. Using this, we show that if a quantum channel is factorized by a direct integral of factors, it must lie in the convex hull of quantum channels which are factorized respectively by the factors in
