We show that braiding transformation is a natural approach to describe quantum entanglement by using the unitary braiding operators to realize entanglement swapping and generate the Greenberger-Horne-Zeilinger states as well as the linear cluster states. A Hamiltonian is constructed from the unitary R{sub i,i+1}({theta},{phi}) matrix, where {phi}={omega}t is time-dependent while {theta} is time-independent. This in turn allows us to investigate the Berry phase in the entanglement space.
