Connes spectral distances, quantum discord and coherence of qubits
Bing-Sheng Lin, Zi-Hao Xu, Ji-Hong Wang +1
We construct spectral triples of one- and two-qubit states using the Hilbert-Schmidt operatorial formulation, and study the Connes spectral distances. We also construct the Dirac o…

Curvature, area and Gauss-Bonnet formula of the Moyal sphere
Han-Liang Chen, Bing-Sheng Lin
We studied some geometric properties of the Moyal sphere. Using the conformal metric of the sphere in ordinary space and the matrix basis, we calculated the scalar curvature, total…
