I joined the Hitachi Cambridge Laboratory in 2012 after the completion of a PhD in Single-Atom Electronics at the University of Cambridge. I was appointed Senior Research Scientist in 2015 and I am currently working in the area of quantum information processing and low-power electronics. One of my main interests is the design and integration of single electron nano-electronic devices in logic circuits for low-power applications. I explore single-electron transistors, single-atom transistors, single-molecule transistors(Nano Lett. 14 5672) and magnetic single-electron transistors as a route towards enhancing the functionality of logic circuits for the Beyond CMOS era. Additionally, I work on the design and development of a silicon-based physical platform to store and process quantum information. My research in this field focuses on developing a CMOS-based quantum computing architecture using state-of-the-art CMOS transistor technology.
My efforts are devoted to simplifying the architecture by reducing the complexity of the quantum circuit using novel high-frequency techniques such as “gate-based radio-frequency reflectometry”. This technique allows charge-sensing without the need of external electrometers and performs at equivalent levels of sensitivity (Nat Commun 6 6084). Besides, it allows probing the dynamics of fast-driven two-levels systems (or qubits) leading to beautiful quantum phenomena such as Landau-Zener-Stuckelberg interferometry (Nano Lett. 16 1614), Pauli spin-blockade (Nano Lett. 15 4622, PRX 5 031024) or Sisyphus dissipation (Nat Commun 6 6084). Recently, I have been working on integration CMOS digital and quantum electronics to facilitate data management in large scale quantum processors (Phys. Rev. Applied 9, 054016).
