The first environment is a two level system coupled to a bosonic bath. And the second one is a damped harmonic oscillator. Based on a unitary transformation, we find that the decoherence of the qubit can be reduced with increasing temperature $T$ in the first case, which agree with the results in [Phys. Rev. Lett. 100, 120401], whereas, it can not be reduced with $T$ in the second case. In both cases, the qubit dynamics are changed substantially as the coupling increases or finite detuning appears.", "revisions": [ { "version": "v2", "updated": "2013-11-04T16:38:58.000Z" } ], "analyses": { "keywords": [ "quantum decoherence", "bath temperature", "first environment", "bosonic bath", "damped harmonic oscillator" ], "tags": [ "journal article" ], "publication": { "journal": "Chemical Physics Letters", "year": 2010, "month": "Nov", "volume": 500, "number": 4, "pages": 256 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010CPL...500..256H" } } }
