Schrdinger Cat States in a Mesoscopic Josephson Junction

  • Department of Applied Physics, Beijing Institute of Technology, Beijing 100081

  • Received Date:1999-05-26
    Abstract
  • To study the nonclassical effects of the mesoscopic Josephson junction in the presence of a nonclassical microwave, the mesoscopic Josephson junction and the field were both treated quantum mechanically, and the external field approximation was used. It is shown that if the external field is in the coherent state and the state of the junction is initially prepared in the vacuum state, the state of the junction can evolve into a quantum superposition of two coherent states. The Schrdinger cat states can be produced in a mesoscopic Josephson junction.
