Pathophysiology, 2021 Voltage-gated channels are crucial in action potential initiation and propagation and there are many diseases and disorders related to them. Additionally, the classical mechanics are the main mechanics used to describe the function of the voltage-gated ...

Operational characterization of incompatibility of quantum channels with quantum state discrimination [PDF]
Physical Review A, 2019 A collection of quantum channels is called incompatible if they cannot be obtained as marginals from a single channel. No-cloning theorem is the most prominent instance of incompatibility of quantum channels. We show that every collection of incompatible

Probabilistic teleportation and entanglement matching [PDF]
, 1999 Teleportation may be taken as sending and extracting quantum information through quantum channels. In this report, it is shown that to get the maximal probability of exact teleportation through partially entangled quantum channels, the sender (Alice ...

Coherence in logical quantum channels [PDF]
New Journal of Physics, 2019 We study the effectiveness of quantum error correction against coherent noise. Coherent errors (for example, unitary noise) can interfere constructively, so that in some cases the average infidelity of a quantum circuit subjected to coherent errors may ...

Identifying the Information Gain of a Quantum Measurement [PDF]
, 2013 We show that quantum-to-classical channels, i.e., quantum measurements, can be asymptotically simulated by an amount of classical communication equal to the quantum mutual information of the measurement, if sufficient shared randomness is available. This

Quantum Information Processing, 2021 The reliability of quantum channels for transmitting information is of profound importance from the perspective of quantum information. This naturally leads to the question as how well a quantum state is preserved when subjected to a quantum channel. We propose a measure of quantumness of channels based on non-commutativity of quantum states that is ...

Approaches for approximate additivity of the Holevo information of quantum channels [PDF]
Physical Review A, 2017 We study quantum channels that are close to another channel with weakly additive Holevo information and derive upper bounds on their classical capacity.

Channel activation of CHSH nonlocality
New Journal of Physics, 2020 Quantum channels that break CHSH nonlocality on all input states are known as CHSH-breaking channels. In quantum networks, such channels are useless for distributing correlations that can violate the CHSH Inequality.

Quantum channels as a categorical completion [PDF]
Logic in Computer Science, 2019 We propose a categorical foundation for the connection between pure and mixed states in quantum information and quantum computation. The foundation is based on distributive monoidal categories. First, we prove that the category of all quantum channels is
