摘要：

An error prevention procedure based on two-particle encoding is proposed for protecting an arbitrary unknown quantum state from dissipation, such as phase damping and amplitude damping. The schemes, which exhibits manifestation of the quantum Zeno effect; is effective whether quantum bits are decohered independently or cooperatively. We derive the working condition of the scheme, and argue that this procedure has feasible practical implementation.
