Abstract: | In the measurement-based model of quantum computing, a one-way
quantum computer consisting of many qubits can be immersed in a
common environment as a simple decoherence mechanism. This paper
studies the dynamics of entanglement witness for 3-qubit cluster
states in the common environment. The result shows that environment
can induce an interesting feature in the time evolution of the
entanglement witness: i.e., the periodical collapse and revival of
the entanglement dynamics. |
