A note on unitary invariance of Connes spectral distances of quantum states
Bing-Sheng Lin, Ji-Hong Wang, Zhi-Kang You
In this paper, we study the properties of Connes spectral distances between quantum states under unitary transformations. We mainly focus on spectral triples with matrix algebras a…

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…
