Superconducting circuits have proven to be one of the most promising platforms for quantum computing and sensing applications with Josephson junctions as one of their fundamental building blocks. Therefore, a reliable fabrication process and characterization apparatus of these components is of crucial importance for every experimental group in this field.
Traditional characterization of...

Devices and methods of quantum information science can bring significant upgrades to current and future particle physics detectors. In particular, I will discuss experiments testing the hypothesis that dark matter is composed of very light particles, detectable as an effective field with a specific frequency set by their mass. As the signal to noise ratio is very poor in these experiments, new...

The challenges of modern fundamental physics lie in low energy phenomena, such as gravitational waves, cosmological inflation and dark matter. Indeed, different phenomena in astronomy (such as radio burst sources, cosmic microwave background, and GHz-peaked radio sources) need the development of sensitive bolometers operating in the GHz-THz bands. Furthermore, low energy particle physics...

Recent particle physics experiments requiring excellent energy resolution involve cryogenic detector arrays composed of hundreds of detector pixels, such as Transition Edge Sensors (TESs). To preserve the intrinsically excellent energy resolution of these detector arrays while maintaining minimal system complexity, a broadband, multiplexed read-out chain, with minimal noise addition is...

We present the design of a hybrid photon number-resolving detector (PNRD) on a lithium niobate-on-insulator (LNOI) platform, aiming to combine superconducting nanowire single-photon detectors (SNSPDs) in a multiplexed configuration for high-fidelity quantum sensing. Finite element method (FEM) simulations have been conducted to assess key performance factors such as propagation losses,...

Superconducting detectors are currently being developed, optimised and deployed for all forms of physics experiments due to their incredible performance that combines moderate-to-elevate energy resolution, time and spatial resolution with high quantum efficiency and effectively near-zero dark counts. At the Pisa section we are moving the first steps in detector design and fabrication, with the...

In the last years, gravitational-wave (GW) Earth-based detectors have seen a great improvement in sensitivity, leading to the detection of more than 100 events during the joint observing runs of the LIGO-Virgo-KAGRA (LVK) Collaboration. This has opened the way to a completely new field of study, i.e. multimessenger astrophysics.

Quantum noise is a fundamental limitation in gravitational wave detectors, restricting their sensitivity and scientific reach. To overcome this challenge, current detectors rely on frequency-dependent squeezing, implemented using long filter cavities to reduce quantum noise across a broad frequency range. While effective, this approach is difficult to scale, particularly for next-generation...

The sensitivity of future Gravitational Wave (GW) detectors, such as the Einstein Telescope (ET), will be significantly limited by various noise sources, particularly magnetic noise, especially at low frequencies (from a few Hz to around 100 Hz). Magnetic noise arises from the interaction between environmental magnetic fields and magnetized elements, such as magnet-coil actuators. These...
