  DECAY OF QUANTUM COHERENCES UNDER THE INFLUENCE OF A THERMAL HEATBATH - SCHRODINGER CAT STATES AT FINITE TEMPERATURE

  , JOURNAL OF MODERN OPTICS, Vol: 39, Pages: {1609-1614}-{1609-1614}, ISSN: 0950-0340

  Recently several methods have been proposed for generation of superposition (Schrodinger cat) states in microwave cavities. At microwave frequencies thermal photons can significantly affect statistical properties of superposition states. In the present letter we study the influence of a thermal heatbath on non-classical properties of quantum superposition states. We show that at non-zero temperatures the loss of quantum coherences is much faster than at zero temperature and that the sensitivity of the quantum coherence to the presence of thermal photons can lead to some difficulties in the preparation of Schrodinger cat states in microwave cavities unless the temperature of the microwave cavity is sufficiently low.

  Scheme for direct observation of the Wigner characteristic function in cavity QED

  , PHYSICAL REVIEW A, Vol: 58, Pages: {R65-R68}-{R65-R68}, ISSN: 1050-2947

  We suggest a quantum state reconstruction scheme. Our proposal is applicable to the field inside a microwave cavity as well as to the harmonic motion of a trapped atom. It will be shown that the inversion of two-level atoms after a resonant interaction with a coherently displaced quantum state is directly related to the Wigner characteristic function of the initial state. This method neither requires the preparation of atoms in a quantum superposition of the upper and lower energy levels nor heavy numerical processing of the measured data. We demonstrate the reconstruction scheme for the example of a Schrodinger-cat superposition state.

  Quantum noise in optical beam propagation in distributed amplifiers

  , OPTICS COMMUNICATIONS, Vol: 130, Pages: {377-384}-{377-384}, ISSN: 0030-4018

  Quantum effects on optical beam propagation in a gain medium having distributed loss are analyzed using an amplifier-attenuator array model. For the amplifier-attenuator set, the Wigner function of the output field is related to that of the input field by a convolution law. Using this, we derive the Fokker-Planck equation for the beam propagation in the distributed amplifier with loss, and the added quantum noise is analyzed by solving this equation. When the amplification just compensates the attenuation, the mean amplitude of the signal does not change but the mean energy increases due to the added noise. Even in this case, the photon number variance can be reduced when a proper phase-sensitive reservoir is incorporated.
