Hi 👋🏻 I’m Andrea, a quantitative researcher and quantum physicist.
I completed my PhD in 2023 at Scuola Normale Superiore (Pisa, Italy), conducting research on experimental superconducting quantum systems. In the fall of 2022, I interned at Google (Santa Barbara, US), working with the Quantum AI team on Josephson parametric amplifiers and qubit readout.
I have authored or co-authored nearly a dozen peer-reviewed publications and have served as referee for various physics journals, covering topics ranging from mesoscopic physics to quantum computing.
In 2024, I transitioned to quantitative finance and started working as a quantitative researcher.

My PhD thesis
In the last decades, superconducting circuits have explosively advanced, enabling the routine exploitation of quantum effects in solid-state quantum technologies. The Josephson effect underlies this development, yet many questions persist. My PhD thesis explores fundamental and applied aspects of superconducting circuits using Josephson weak-links. Titled “Superconducting circuits with metallic and semiconducting weak-links”, it can be accessed here.
Amplification at the quantum limit
At Google, the Quantum AI team is building a useful quantum computer using superconducting circuits. Making a quantum computer function well involves fine-tuning different parts, and parametric amplifiers are key components as they allow fast single-shot readout of superconducting qubits. However, optimising their performance is not an easy task. For more on my work with the Quantum AI team, see this Google blog post.
A quantum phase battery
A classical battery converts chemical energy into a persistent voltage bias capable of powering electronic circuits. Similarly, a phase battery is a quantum device that provides a continuous phase bias to the wavefunction of a superconducting circuit. In our research, we achieved the first demonstration of a phase battery in a nanowire-based Josephson junction. Read more in Nature Nanotechnology.
Half-integer Shapiro steps
Shapiro steps are quantized voltage plateaus that emerge in a Josephson junction under an alternating bias, forming the foundation of the metrological voltage standard. Our research uncovered an unexpected half-integer quantization, and we delved into its origin in a Josephson junction based on a nanoflag. Read more here.
Light diffraction at the Golden Gate Bridge12 Feb 2024
I recently dedicated some time to organizing and reviewing the many photos I captured last year. Personally, I find this process quite tedious: I end up jumping from one picture to another in collections of almost-but-not-totally identical shots, attempting to identify the best one. The same destiny awaited some photos taken at the Golden Gate Bridge. However, one of them made my post-processing session much more enjoyable. Since it is related to physics, my first love, I felt compelled to write about it and it gave me an excuse to procrastinate again! (...)
My first post17 Jan 2024
Hey there, reader! Exciting times – this marks my first blog post after giving my website a much-needed makeover. It lingered on my to-do list, patiently waiting for my PhD to wrap up. Built with Hugo and styled with Tailwind, the entire experience was a rediscovery after a prolonged absence from serious online development. I also included a new Photography section, powered by this excellent module. I’ll make an effort to keep it updated, as I no longer feel other platforms are suitable for sharing my work. (...)
