    "abstract": "We study the time evolution of a qubit linearly coupled with a quantum\nenvironment under a sequence of short pi pulses. Our attention is focused on\nthe case where qubit-environment interactions induce the decoherence with\npopulation decay. We assume that the environment consists of a set of bosonic\nexcitations. The time evolution of the reduced density matrix for the qubit is\ncalculated in the presence of periodic short pi pulses. We confirm that the\ndecoherence is suppressed if the pulse interval is shorter than the correlation\ntime for qubit-environment interactions.",
