IRIDE: Interdisciplinary research infrastructure based on dual electron linacs and lasers

2014

This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of sci…

Bimodal Approach for Noise Figures of Merit Evaluation in Quantum-Limited Josephson Traveling Wave Parametric Amplifiers

2022

The advent of ultra-low noise microwave amplifiers revolutionized several research fields demanding quantum-limited technologies. Exploiting a theoretical bimodal description of a linear phase-preserving amplifier, in this contribution we analyze some of the intrinsic properties of a model architecture (i.e., an rf-SQUID based Josephson Traveling Wave Parametric Amplifier) in terms of amplification and noise generation for key case study input states (Fock and coherents). Furthermore, we present an analysis of the output signals generated by the parametric amplification mechanism when thermal noise fluctuations feed the device.

Noise Figures of Merit of rf-SQUID-based Josephson Travelling Wave Parametric Amplifiers

2021

The characterization of the rf-SQUID-based JTWPA in terms of its noise figure and gain for different input states (Fock states or Coherent states) has been carried out. The spectral distribution of the noise temperature Tn and gain G presents a region where the amplifier has a relatively high gain with a thermal noise that can go beyond the standard quantum limit =ℏ/2 (valid only for single mode input states [44]) as shown in Fig. 3. The TWJPA is here biased in its 3WM regime and pumped at p = 12 GHz.
