چکیده
We perform noise spectroscopy of a Josephson parametric oscillator (JPO) by implementing microwave homodyne interferometric measurement scheme. observe the fluctuations in self-oscillating output field JPO for long 10-s time interval single-shot and characterize phase amplitude noise. Furthermore, we investigate effects pump strength on power spectra JPO. find strong with $1/{f}^{2}$ characteristic spectrum, which are suppressed increasing strength.

A low-noise series-array Josephson junction parametric amplifier
We have obtained parametric gain at 19 GHz from a distributed Josephson junction parametric amplifier whose active gain medium consists of a series array of 1000 Josephson junctions embedded in a coplanar waveguide. When cooled to 1.7 K the amplifier provides 16 dB gain in a mode where the internally generated double sideband noise referred to input is 0.560.1 K. This noise is consistent with N...
متن کاملEffects of parametric noise on a nonlinear oscillator
We study a model of a nonlinear oscillator with a random frequency and derive the asymptotic behavior of the probability distribution function when the noise is white. In the small damping limit, we show that the physical observables grow algebraically with time before the dissipative time scale is reached, and calculate the associated anomalous diffusion exponents. In the case of colored noise...
متن کاملSingle-shot read-out of a superconducting qubit using a Josephson parametric oscillator
We propose and demonstrate a read-out technique for a superconducting qubit by dispersively coupling it with a Josephson parametric oscillator. We employ a tunable quarter wavelength superconducting resonator and modulate its resonant frequency at twice its value with an amplitude surpassing the threshold for parametric instability. We map the qubit states onto two distinct states of classical ...
متن کاملNoise characteristics of a non-degenerate Optical Parametric Oscillator - Application to quantum noise reduction
2014 A semi-classical analysis of the noise characteristics of a non degenerate, above threshold, optical parametric oscillator is presented, yielding expressions for the quantum fluctuations of the output field intensities and phases. Particular emphasis is given to the study of the noise on the intensity difference between the two generated fields. The effect of losses, unbalance, detunings a...
