摘　　要：Quantum decoherence behavior is observed and studied on a 2 qubit NMR quantum computer. Experimental results show a good agreement between theory and experiment. The scheme can be generalized to the case that the environment is composed of N independent qubits.Quantum decoherence behavior is observed and studied on a 2 qubit NMR quantum computer.
