Efficient Characterization of Quantum Evolutions via a Recommender System [PDF]
Quantum, 2021 We demonstrate characterizing quantum evolutions via matrix factorization algorithm, a particular type of the recommender system (RS). A system undergoing a quantum evolution can be characterized in several ways.

QUANTUM DISCORD AND QUANTUM COMPUTING — AN APPRAISAL [PDF]
International Journal of Quantum Information, 2011 We discuss models of computing that are beyond classical. The primary motivation is to unearth the cause of non-classical advantages in computation. Completeness results from computational complexity theory lead to the identification of very disparate problems, and offer a kaleidoscopic view into the realm of quantum enhancements in computation ...

Monogamy properties of quantum correlations in neutrino oscillations
European Physical Journal C: Particles and Fields, 2023 The monogamy relation of quantum states has limited the shareability properties of quantum resources in multiparty quantum systems. It plays a vital role in information distribution and transformation over many sites in quantum communications.

Analysis of Quantum Correlations Obtained Using Local Optimal Universal Asymmetric Cloners
Entropy, 2022 We apply the local optimal universal asymmetric cloning machine on an initially pure entangled state of two qubits. As output, we obtain two final states which present quantum correlations.

Sharma–Mittal quantum discord [PDF]
Quantum Information Processing, 2019 We demonstrate a generalization of quantum discord using a generalized definition of von-Neumann entropy, which is Sharma-Mittal entropy; and the new definition of discord is called Sharma-Mittal quantum discord. Its analytic expressions are worked out for two qubit quantum states as well as Werner, isotropic, and pointer states as special cases. The R{

Quantum Discord: A Measure of the Quantumness of Correlations [PDF]
Physical Review Letters, 2001 Two classically identical expressions for the mutual information generally differ when the systems involved are quantum. This difference defines the quantum discord. It can be used as a measure of the quantumness of correlations. Separability of the density matrix describing a pair of systems does not guarantee vanishing of the discord, thus showing ...

Squeezing of Primordial Gravitational Waves as Quantum Discord
Universe, 2020 We investigate the squeezing of primordial gravitational waves (PGWs) in terms of quantum discord. We construct a classical state of PGWs without quantum discord and compare it with the Bunch−Davies vacuum.
