On this website, you will find my resume, a searchable list of my publications and information on my research (under construction). If anything triggers your attention, feel free to contact me.
Great news! NWO awarded an Open Technology Program grant to a team of PI comprising Carmina Almudever, Giordano Scapucci, Menno Veldhorst, and myself, all from TU Delft.
Quantum computers hold the promise to solve problems that are intractable even by the most powerful supercomputers. With a budget of 1.2 M€ and over the span of 5 years, we will investigate how to build a practical quantum computer, and move from the current lab prototypes towards quantum computers with the capability to solve real-life problems. Building on the expertise of a multi-disciplinary team, we will address the challenges of building a large-scale quantum computer by attacking the problems at several levels, ranging from material engineering and quantum operations up to cryogenic control electronics and computer architecture. Fats progress will be facilitated by collaborating with industrial partners: Intel, the world-leading computing company, that will contribute to the fabrication of large qubit arrays, and Bluefors, leader in cryogenic refrigeration, that will participate in the development and deployment of cryogenic electronics to interface with the qubits.
Stay tuned to hear about the progress! And drop a message if you are interested to participate in this research journey as a Ph.D. student!
The Distinguished Lecturer program of the IEEE Solid-State Circuit Society (SSCS) provides world-renowned experts in the field of integrated circuits (IC) to give lectures and seminars at regional and local venues around the world. The aim is to educate and spread knowledge on a wide range of topics focusing on state-of-the-art IC technology.
I am very glad to participate in this program, and I can’t wait to take the chance to spread the word about research topics close to my heart. To this extent, I am impatient to give these talks about cryogenic CMOS electronics for quantum computation and fully-integrated references:
- Towards Large-Scale Quantum computers: Cryogenic CMOS for Scalable Quantum Computation
- To XTAL or not to XTAL: the quest for fully integrated frequency references
- References for smart sensors
To arrange a visit in the context of the SSCS DL program, you can contact me directly or visit the SSCL DL website.
Recently, Rosario and I wrote a popular-science article on cryo-CMOS circuits for quantum computing (and other cool applications). It was published in the last edition of Maxwell, the magazine of the Electrical Engineering study association (ETV) of the TU Delft. You can find it here:
Designing a quantum computer is not an easy task. Recently, we developed a methodology (and the relative tools) to co-design electronic circuits and quantum bits (qubits).
It will be presented at the DATE 2018 conference (Design, Automation and Test in Europe) in March in Dresden (Germany).

I will give an invited talk at SiQIP 2017 with title “Cryo-CMOS Electronics for Scalable Quantum Computing” in Lancaster in September.
Coming August, my group will have several contributions at the Silicon Quantum Electronics Workshop in Hillsboro (OR). This is the reference workshop for the community working on silicon qubits, i.e. basically spin qubits.
We will have 2 presentations:
- Jeroen van Dijk: Trade-offs in engineering a scalable cryogeni controller for solid-state spin-qubits
- Bishnu Patra: Cryogenic frequency synthesis for qubit control: Analysis and Design
and several posters:
- Rosario M. Incandela, Edoardo Charbon, Fabio Sebastiano: A 7-K noise temperature cryogenic CMOS LNA for scalable RF readout of spin qubits
- M. Mehrpoo, F. Sebastiano, E. Charbon, M. Babaie: Design Considerations of Cryo-RFICs for Superconducting Qubits Readout
- Andrea Ruffino, Masoud Babaie, Fabio Sebastiano, Edoardo Charbon: Cryo-CMOS circulators for spin and superconducting qubits
I have been invited at DAC (Design Automation Conference) to give a talk on our work on cryo-CMOS for quantum computing. In particular, I will focus both on my group’s effort in design tools that can enable the design of cryogenic circuits for quantum computers, and on what the design automation industry will have to do to make quantum computers possible.
