WebFeb 1, 2024 · The objective of this paper is to present a multi-fidelity physics informed deep learning framework that addresses both the limitations discussed above. Unlike some of the previous studies, it is assumed that the data-generation process for the high-fidelity data is unknown. In quantum mechanics, notably in quantum information theory, fidelity is a measure of the "closeness" of two quantum states. It expresses the probability that one state will pass a test to identify as the other. The fidelity is not a metric on the space of density matrices, but it can be used to define the Bures metric on … See more Given two random variables $${\displaystyle X,Y}$$ with values $${\displaystyle (1,...,n)}$$ (categorical random variables) and probabilities $${\displaystyle p=(p_{1},p_{2},\ldots ,p_{n})}$$ See more Unitary invariance Direct calculation shows that the fidelity is preserved by unitary evolution, i.e. for any See more Given two density matrices ρ and σ, the fidelity is defined by where, for a positive semidefinite matrix $${\displaystyle M}$$, $${\displaystyle {\sqrt {M}}}$$ denotes its unique positive square root, … See more parker global core catalog
