Squeezing Effect on Entanglement Swapping: A Quantum Trajectory Approach
Jin Woo Jun · Journal of the Korean Physical Society · 2018
Using the results of our previous work (J. Korean Phys. Soc. 56 , 10 (2010)), we calculate the negativity N and the geometric discord G of the final qubits of the entanglement swapping protocol through an amplitude-damping multi-qubit channel interacting with a squeezed thermal bath. Our numerical results confirm that the squeezing suppresses the decay rate of quantum coherence.
