    "abstract": "The pulse control of decoherence in a qubit interacting with a quantum\nenvironment is studied with focus on a general case where decoherence is\ninduced by both pure dephasing and population decay. To observe how the\ndecoherence is suppressed by periodic pi pulses, we present a simple method to\ncalculate the time evolution of a qubit under arbitrary pulse sequences\nconsisting of bit-flips and/or phase-flips. We examine the effectiveness of the\ntwo typical sequences: bb sequence consisting of only bit-flips, and bp\nsequence consisting of both bit- and phase-flips. It is shown that the\neffectiveness of the pulse sequences depends on a relative strength of the two\ndecoherence processes especially when a pulse interval is slightly shorter than\nqubit-environment correlation times. In the short-interval limit, however, the\nbp sequence is always more effective than, or at least as effective as, the bb\nsequence.",
