Quantum fluctuations in intrinsic bistability of a two-level system
Y. Ben-Aryeh, Charles M. Bowden · Journal of the Optical Society of America B · 1991
The quantum fluctuations in intrinsic bistability of a two-level system are calculated by means of Einstein relations. All the second moments of the dipole operators are calculated, and the statistical properties of the reaction field are studied. It is found that quantum noise that is above the standard quantum limit is inherent in the reaction field.
