Phonon-mediated quantum discord in dark solitons

The European Physical Journal Plus, 2019
We investigate the quantum correlation dynamics in dark-soliton qubits with a special attention to quantum discord. Recently, dark-soliton qubit exhibiting appreciably long lifetime is proved to be an excellent candidate for information processing ...

Quantum Discord of Certain Two-Qubit States

International Journal of Theoretical Physics, 2019
Quantum discord is an effective measure of quantum correlation introduced by Olliver and Zurek. We evaluate analytically the quantum discord for a large family of non-X-states.

Study on estimating quantum discord by neural network with prior knowledge

Quantum Information Processing, 2019
Machine learning has achieved success in many areas because of its powerful fitting ability, so we hope it can help us to solve some significant physical quantitative problems, such as quantum correlation. In this research, we will use neural networks to

Dynamics of super quantum discord and optimal dense coding in quantum channels

Journal of Physics A: Mathematical and Theoretical, 2018
Quantum discord (QD), super quantum discord (SQD) and optimal dense coding at entangled states of three types of quantum channels, are investigated. The used models include: two-qubit spin squeezing, the two-qubit Heisenberg XYZ model with decoherency ...
