Dense Coding Capacity in Correlated Noisy Channels with Weak Measurement
Jin-Kai Li, Kai Xu, Guo-Feng Zhang
Capacity of dense coding via correlated noisy channel is greater than that in uncorrelated noisy channel. It is shown that weak measurement and reversal measurement can make furthe…

Thermal Coherence of Heisenberg Model With Dipole Interaction and Magnetic External Field
Jin-Kai Li, Guo-Feng Zhang
The dynamics of coherence in a two-qubit Heisenberg XXX model with magnetic field in the presence of the intrinsic decoherence is investigated. We discuss the influence of dipole p…
