The power of entangled quantum channels [PDF]
arXiv, 2001 All communication channels are at bottom quantum mechanical. Quantum mechanics contributes both obstacles to communication in the form of noise, and opportunities in the use of intrinsically quantum representations for information. This paper investigates the trade-off between power and communication rate for coupled quantum channels.

Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst
Advanced Functional Materials, EarlyView.This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

The decreasing property of relative entropy and the strong superadditivity of quantum channels [PDF]
Quantum Information and Computation 7 (2009) 594-609, 2008 We argue that a fundamental (conjectured) property of memoryless quantum channels, namely the strong superadditivity, is intimately related to the decreasing property of the quantum relative entropy. Using the latter we first give, for a wide class of input states, an estimation of the output entropy for phase damping channels and some Weyl quantum ...

Assessing the performance of quantum repeaters for all phase-insensitive Gaussian bosonic channels
New Journal of Physics, 2016 One of the most sought-after goals in experimental quantum communication is the implementation of a quantum repeater. The performance of quantum repeaters can be assessed by comparing the attained rate with the quantum and private capacity of direct ...

Markov Chain-Like Quantum Biological Modeling of Mutations, Aging, and Evolution
Life, 2015 Recent evidence suggests that quantum mechanics is relevant in photosynthesis, magnetoreception, enzymatic catalytic reactions, olfactory reception, photoreception, genetics, electron-transfer in proteins, and evolution; to mention few.

Operational resource theory of quantum channels
Physical Review Research, 2020 Quantum resource theories have been widely studied to systematically characterize the nonclassicality of quantum systems. Most resource theories focus on quantum states and study their interconversions.

Entanglement required in achieving entanglement-assisted channel capacities
, 2002 Entanglement shared between the two ends of a quantum communication channel has been shown to be a useful resource in increasing both the quantum and classical capacities for these channels.

Advanced Functional Materials, EarlyView.Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...

Visually quantifying single-qubit quantum memory
Physical Review ResearchTo store quantum information, quantum memory plays a central intermediate ingredient in a network. The minimal criterion for a reliable quantum memory is the maintenance of the entangled state, which can be described by the non-entanglement-breaking (non-

Coherence generating power of unitary transformations via probabilistic average
, 2018 We study the ability of a quantum channel to generate quantum coherence when it applies to incoherent states. Based on probabilistic averages, we define a measure of such coherence generating power (CGP) for a generic quantum channel, based on the ...
