The power of one clean qubit in supervised machine learning [PDF]
Scientific Reports, 2023 This paper explores the potential benefits of quantum coherence and quantum discord in the non-universal quantum computing model called deterministic quantum computing with one qubit (DQC1) in supervised machine learning.

A new entropic quantum correlation measure for adversarial systems [PDF]
Scientific Reports, 2023 Quantum correlation often refers to correlations exhibited by two or more local subsystems under a suitable measurement. These correlations are beyond the framework of classical statistics and the associated classical probability distribution.

Operational interpretations of quantum discord [PDF]
Physical Review A, 2011 Quantum discord quantifies non-classical correlations going beyond the standard classification of quantum states into entangled and unentangled ones. Although it has received considerable attention, it still lacks any precise interpretation in terms of some protocol in which quantum features are relevant.

Quantum correlation of microwave two-mode squeezed state generated by nonlinearity of InP HEMT [PDF]
Scientific Reports, 2023 This study significantly concentrates on cryogenic InP HEMT high-frequency circuit analysis using quantum theory to find how the transistor nonlinearity can affect the quantum correlation of the modes generated.

Quantum Discord for d⊗2 Systems. [PDF]
Sci Rep, 2015 AbstractWe present an analytical solution for classical correlation, defined in terms of linear entropy, in an arbitrary "Equation missing" system when the second subsystem is measured. We show that the optimal measurements used in the maximization of the classical correlation in terms of linear entropy, when used to calculate the quantum discord in ...

Bell Diagonal and Werner State Generation: Entanglement, Non-Locality, Steering and Discord on the IBM Quantum Computer [PDF]
Entropy, 2021 We propose the first correct special-purpose quantum circuits for preparation of Bell diagonal states (BDS), and implement them on the IBM Quantum computer, characterizing and testing complex aspects of their quantum correlations in the full parameter ...

Quantum correlations beyond entanglement in a classical-channel model of gravity [PDF]
Scientific Reports, 2022 A direct quantization of the Newtonian interaction between two masses is known to establish entanglement, which if detected would witness the quantum nature of the gravitational field.

Non-commutativity measure of quantum discord. [PDF]
Sci Rep, 2016 AbstractQuantum discord is a manifestation of quantum correlations due to non-commutativity rather than entanglement. Two measures of quantum discord by the amount of non-commutativity via the trace norm and the Hilbert-Schmidt norm respectively are proposed in this paper.

Composite Discordant States and Quantum Darwinism. [PDF]
Entropy (Basel), 2022 The framework of Quantum Darwinism strives at characterizing the quantum-to-classical transition by introducing the concept of redundancy of information—as measured by Mutual Information—that a set of observers would acquire on the state of a physical system of interest.
