Solving the inverse parametric problem
Michele Cortinovis, Fabio Lingua, David B. Haviland
We present a method to calculate the frequency components of a pump waveform driving a parametric oscillator, which realizes a desired frequency mixing or scattering between modes.…
Continuous-variable two-dimensional cluster states in the microwave domain
Fabio Lingua, Michele Cortinovis, J. C. Rivera Hernández +1
We demonstrate the experimental realization of two-dimensional, continuous variable (CV) cluster states between 191 microwave frequency modes. This result is obtained by exposing v…
Non-reciprocal scattering in a microwave frequency comb
Christoph L. Bock, J. C. Rivera Hernández, Fabio Lingua +1
We investigate nonreciprocal scattering within the modes of a microwave frequency comb. Adjusting the pump frequencies, amplitudes, and phases of a Josephson parametric oscillator,…
Continuous-variable square-ladder cluster states in a microwave frequency comb
Fabio Lingua, J. C. Rivera Hernández, Michele Cortinovis +1
We describe an experiment demonstrating the generation of three independent square-ladder continuous-variable cluster states with up to 94 qumodes of a microwave frequency comb. Th…
Sensing force gradients with cavity optomechanics while evading backaction
Elisabet K. Arvidsson, Ermes Scarano, August K. Roos +2
We study force-gradient sensing with a coherently driven mechanical resonator and phase-sensitive detection of motion through the two-tone backaction evading measurement of cavity…
