Quantum control of entanglement and information of two solid state qubits: remote control of dephasing

Shang-Bin Li, Jing-Bo Xu

We investigate the scheme for controlling information characterized by Von-Neumann entropy and the stationary state entanglement characterized by concurrence of two solid state qub…

Magnetic field effects on the optimal fidelity of standard teleportation via the two qubits Heisenberg XX chain in thermal equilibrium

Shang-Bin Li, Jing-Bo Xu

We study the two qubits Heisenberg XX chain with magnetic impurity in the presence of the external magnetic field and calculate the optimal fidelity of standard teleportation via t…
