| Abstract |
It is shown that the quantum jumps in the photon number nˆ from zero to one or more photons induced by backaction evasion quantum nondemolition measurements of a quadrature component xˆ of the vacuum light field state are strongly correlated with the quadrature component measurement results. This correlation corresponds to the operator expectation value <xˆ nˆ xˆ > which is equal to one-fourth for the vacuum even though the photon number eigenvalue is zero. Quantum nondemolition measurements of a quadrature component can thus provide experimental evidence of the nonclassical operator ordering dependence of the correlations between photon number and field components in the vacuum state.
