    "abstract": "The time evolution of entanglement for excitons in two quantum dots embedded\nin a single mode cavity is studied in a ``spin-boson\u0027\u0027 regime. It is found that\nalthough with the dissipation from the boson mode, the excitons in the two\nquantum dots can be entangled by only modulating their energy bias $\\epsilon$\nunder the influence of external driving magnetic field. Initially, the two\nexcitons are prepared in a pure separate state. When the time-dependent\nmagnetic field is switched on, a highly entangled state is produced and\nmaintained even in a very long time interval. The mechanism may be used to\ncontrol the quantum devices in practical applications.",
