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.

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.

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.

Entanglement harvesting and quantum discord of alpha vacua in de Sitter space [PDF]
Journal of High Energy PhysicsThe CPT invariant vacuum states of a scalar field in de Sitter space, called α-vacua, are not unique. We explore the α-vacua from the quantum information perspective by a pair of static Unruh-DeWitt (UDW) detectors coupled to a scalar field with either ...

Revealing Tripartite Quantum Discord with Tripartite Information Diagram
Entropy, 2017 A new measure based on the tripartite information diagram is proposed for identifying quantum discord in tripartite systems. The proposed measure generalizes the mutual information underlying discord from bipartite to tripartite systems, and utilizes ...

Channel discord and distortion
New Journal of Physics, 2021 Discord, originally notable as a signature of bipartite quantum correlation, in fact can be nonzero classically, i.e. arising from noisy measurements by one of the two parties.

Identification of Unentangled–Entangled Border in the Luttinger Liquid Phase
Crystals, 2019 Quantum discord and entanglement are both criteria for distinguishing quantum correlations in a quantum system. We studied the effect of the transverse magnetic field on the quantum discord of the one-dimensional spin-1/2 XX model.

IEEE Photonics Journal, 2018 We investigate the decay properties of the quantumness including quantum entanglement, quantum discord, and quantum coherence for two photonic qubits, which are partially entangled in their orbital angular momenta, through Kolmogorov turbulent atmosphere.
