The successful generation and detection of squeezed electromagnetic radiation at optical frequencies1 promise to open the door to the exploration of new quantum phenomena, some of which may be technologically useful.2 The generation and detection of squeezed radiation at low frequencies would also open the door to the observation of novel quantum phenomena. We report here on a Josephson parametric amplifier which appears to be well behaved and may be suitable for generating squeezed coherent microwave radiation. The amplifier was operated in the four-photon or doubly degenerate mode,3 and thus its operation is akin to that of an optical four-wave mixer.1The successful generation and detection of squeezed electromagnetic radiation at optical frequencies1 promise to open the door to the exploration of new quantum phenomena, some of which may be technologically useful.2 The generation and detection of squeezed radiation at low frequencies would also open the door to the observation of novel quantum phenomena.

Squeezed-state generation using a Josephson parametric amplifier

Bernard Yurke

Josephson-junction parametric amplifiers are promising candidates as sources of squeezed microwave radiation. Here, an analysis of one such amplifier, a radio-frequency superconducting quantum interference device operated in either the three-photon or the four-photon mode, is presented. Expressions for the amount of squeezing that could be obtained from such a device are derived in terms of the basic device parameters.

Spectral analysis of a four mode cluster state

S. L. W. Midgley, M. K. Olsen

We theoretically evaluate the squeezed joint operators produced in a single optical parametric oscillator which generates quadripartite entangled outputs, as demonstrated experimentally by Pysher et al. [1]. Using a linearized fluctuation analysis we calculate the squeezing of the joint quadrature operators below threshold for a range of local oscillator phases and frequencies. These results add to the existing theoretical understanding of this potentially important system.
