Two-time correlators for propagating squeezed microwave fields in transients
Two-time correlators for propagating squeezed microwave fields in transients
We analyze two-time correlators as the most natural characteristic of a propagating quadrature-squeezed field in the transient regime. The considered system is a parametrically driven resonator with a time-dependent drive. Using a semiclassical approach derived from the input-output theory, we develop a technique for calculation of the two-time correlators, which …
