Evaluating radiation impact on transmon qubits in above and underground facilities
Francesco De Dominicis, Tanay Roy, Ambra Mariani +20
Superconducting qubits can be sensitive to abrupt energy deposits caused by cosmic rays and ambient radioactivity. While previous studies have explored correlated effects in time a…
Operating in a deep underground facility improves the locking of gradiometric fluxonium qubits at the sweet spots
Daria Gusenkova, Francesco Valenti, Martin Spiecker +14
We demonstrate flux-bias locking and operation of a gradiometric fluxonium artificial atom using two symmetric granular aluminum (grAl) loops to implement the superinductor. The gr…
Final results of CALDER: Kinetic inductance light detectors to search for rare events
Laura Cardani, Nicola Casali, Ivan Colantoni +6
The next generation of bolometric experiments searching for rave events, in particular for the neutrino-less double beta decay, needs fast, high-sensitivity and easy-to-scale cryog…
A chemically etched corrugated feedhorn array for D-band CMB observations
Stefano Mandelli, Elenia Manzan, Aniello Mennella +19
We present the design, manufacturing, and testing of a 37-element array of corrugated feedhorns for Cosmic Microwave Background (CMB) measurements between and GHz. The…
A Cryogenic Muon Tagging System Based on Kinetic Inductance Detectors for Superconducting Quantum Processors
Ambra Mariani, Laura Cardani, Mustafa Bal +16
Ionizing radiation has emerged as a potential limiting factor for superconducting quantum processors, inducing quasiparticle bursts and correlated errors that challenge fault-toler…
Reducing the impact of radioactivity on quantum circuits in a deep-underground facility
Laura Cardani, Francesco Valenti, Nicola Casali +20
As quantum coherence times of superconducting circuits have increased from nanoseconds to hundreds of microseconds, they are currently one of the leading platforms for quantum info…
Enhanced Athermal Phonon Responsivity in a Kinetic Inductance Detector with Integrated Phonon Collectors
Leonardo Pesce, Alessio Ludovico De Santis, Martino Calvo +10
Cryogenic phonon detectors are adopted in light dark matter searches and coherent elastic neutrino-nucleus scattering experiments as they can achieve low energy thresholds. The pho…
