Quantum entanglement and teleportation in quantum dot
Li-Guo Qin, Li-Jun Tian, Guo-Hong Yang
We study the thermal entanglement and quantum teleportation using quantum dot as a resource. We first consider entanglement of the resource, and then focus on the effects of differ…

The sudden birth and sudden death of thermal fidelity in a two-qubit XY model
Li-Jun Tian, Li-Guo Qin, Ying Jiang +1
We study the energy level crossings of the states and thermal fidelity for a two-qubit system in the presence of a transverse and inhomogeneous magnetic field. It is shown clearly…

Fidelity susceptibility and geometric phase in critical phenomenon
Li-Jun Tian, Chang-Qing Zhu, Hong-Biao Zhang +1
Motivated by recent development in quantum fidelity and fidelity susceptibility, we study relations among Lie algebra, fidelity susceptibility and quantum phase transition for a tw…
