Presentation

The activity at CNR-ISASI is mainly focused on the design, fabrication, and characterization of superconducting quantum devices for magnetic sensing and the relative applications requiring extremely high sensitivity such as biomedicine, quantum computing, nano-magnetism, magnetic microscopy and basic physics experiments. It is worth mentioning the development of low noise SQUID magnetometers that, thanks to their ultra-high sensitivity, have allowed us to realize, in the framework of interdisciplinary project, a large multichannel system for functional brain imaging (magnetoencephalography) working in a clinical environment to study mainly neurodegenerative diseases such as such as preclinical phase of dementia, Alzheimer’s disease, frontotemporal dementia, Parkinson disease, autism spectrum disorders, amyotrophic lateral sclerosis and migraine. In the field of new quantum technologies, the activity is devoted to development of ferromagnetic Josephson junction including a ferromagnetic material for the realization of innovative qubits (ferrotrasmon). The ferrotransmon has been proposed as a scalable alternative to flux-tunable transmon qubits, which have the disadvantage of being sensitive to flux-noise fluctuations.
