摘要

The influence of white and color noise on the outcome of the entanglement swapping process is investigated in a four-qubit system.Critical degree of noise in initial state,that could destroy entanglement in a result state is presented.The entanglement characteristics,such as concurrence,tangle,etc.are compared.Results could be helpful for experiments regarding entanglement swapping as conditions for initial quantum entangled states,to obtain entangled result state.
