Traceable In Situ Microwave Power Measurement at the Cryogenic Device Plane in a Dilution Refrigerator
Paolo Panetta, Andrea Celotto, Alessandro Alocco +7
Accurate knowledge of the microwave power delivered to a cryogenic device under test (DUT) is essential for the characterization and operation of superconducting quantum circuits.…
Device-Agnostic Microwave Noise Metrology for Nonlinear Cryogenic Quantum Devices
Andrea Celotto, Alessandro Alocco, Bernardo Galvano +6
Microwave devices capable of near-quantum-limited signal processing are essential components in the toolbox of solid-state quantum technologies. The manipulation and readout of sin…
JCO: Optimization Framework for Nonlinear Superconducting Circuits Using a Lumped-Element Approach and Harmonic Balance
Emanuele Palumbo, Alessandro Alocco, Andrea Celotto +4
In this contribution we present JosephsonCircuitsOptimizer.jl (JCO), a simulation and optimization framework based on the JosephsonCircuits.jl library for Julia. It models supercon…
Programmable Microwave Cluster States via Josephson Metamaterials
A. Alocco, A. Celotto, E. Palumbo +5
Cluster states are a fundamental resource for continuous-variable quantum computing, enabling measurement-based protocols that can scale beyond the limitations of qubit-based archi…
Towards Quantifying Two-Mode Correlation Linewidths in Quantum Circuits
Alessandro Alocco, Andrea Celotto, Luca Fasolo +7
This paper aims to quantify the linewidth of two-mode correlations in Traveling Wave Parametric Amplifiers (TWPAs). Artifacts induced by data acquisition and processing, such as wi…
Microwave Quantum Radar using a Josephson Traveling Wave Parametric Amplifier
Patrizia Livreri, Emanuele Enrico, Luca Fasolo +6
Detection of low-reflectivity objects can be improved by the so-called quantum illumination procedure. However, quantum detection probability exponentially decays with the source b…
