Observation of two-mode squeezing in the microwave frequency domain.
Continuous variable entanglement between two modes of a radiation field is usually studied at optical frequencies. Here we demonstrate experiments that show the entanglement between microwave photons of different energy in a broadband squeezed beam. We use a Josephson parametric amplifier to generate the two-mode correlated state and detect all four quadrature components simultaneously in a two...

متن کاملObservation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement.
We observe -9.01+/-0.14 dB of squeezing and +15.12+/-0.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. Suzuki et al. have pointed out two main factors in [Appl. Phys. Lett. 89, 061116 (2006)], which degrade the observed squeezing level:phase fluctuation in homodyne measurement and intracavity losses of an optical parametric oscillator for squeezing. We have ...
متن کاملLarge quadrature squeezing at high intensities.
The squeezing properties of a system characterized by large y and y nonlinear susceptibilities and injected classical fields for the two relevant modes are studied as a function of the output power. A large reduction of noise levels well above threshold has been found and a remarkable dependence of the maximum squeezing on the input power has been shown. The possibility of an implementation wit...
متن کاملSqueezing in the multi-mode nonlinear optical state truncation
In this paper, we show that the multi mode qubit states produced by nonlinear optical state truncation exhibit squeezing condition. We restrict our discussions to the two and three mode cases driven by classical external pumpings.
