Sudden transitions of trace distance discord of dipole-dipole coupled two qubits
Zheng-Da Hu, Jicheng Wang, Yixin Zhang +1
We investigate the exact dynamics of trace distance discord by considering two qubits under dephasing whose states belong to a class of states beyond Bell diagonal form. The ne…

Negativity of quantumness and non-Markovianity in a qubit coupled to a thermal Ising spin bath system
Zheng-Da Hu, Yixin Zhang, Ye-Qi Zhang
We propose a scheme to characterize the non-Markovian dynamics and quantify the non-Markovianity via the non-classicality measured by the negativity of quantumness. By considering…
