Cryo-CMOS electrical interfaces for quantum processors
As the qubit count in today’s quantum processors keeps steadily rising, it is increasingly challenging to control and read out such a large number of cryogenic qubits with off-the-shelf room-temperature electronics. Such an approach will soon hit a brick wall due to the limited reliability and the sheer size of the cables interconnecting the quantum processor to its electronic interface for a large-scale quantum computer with thousands or even millions of qubits.
As a scaling-friendly alternative, we propose an electronic controller fabricated using commercial CMOS technology but operating at cryogenic temperatures close to the qubits, thus leveraging the very large scale of integration of the semiconductor industry. In this talk, the main challenges in building the cryo-CMOS electronics for a large-scale quantum computer will be first outlined. Then, several analog/mixed-signal/digital circuits and complex SoCs operating at cryogenic temperature and in combination with qubits will be demonstrated, thus showing that CMOS technology is a viable and necessary element to enable large-scale quantum computing.
Biography of Invited Speaker
Fabio Sebastiano received the B.Sc. and M.Sc. degrees in electrical engineering from University of Pisa, Italy, in 2003 and 2005, respectively, the M.Sc. degree (cum laude) from Sant’Anna School of Advanced Studies, Pisa, Italy, in 2006 and the Ph.D. degree from Delft University of Technology, The Netherlands, in 2011. From 2006 to 2013, he was with NXP Semiconductors Research in Eindhoven, The Netherlands, where he researched fully integrated CMOS frequency references, nanometer temperature sensors, and area-efficient interfaces for magnetic sensors.
In 2013, he joined Delft University of Technology, where he is currently an Associate Professor and the Research Lead of the Quantum Computing Division of QuTech. His main research interests are cryogenic electronics, quantum computing, sensor read-outs, and fully integrated frequency references. Dr. Sebastiano is on the technical program committee of the ISSCC, the RFIC Symposium, and the IMS, and he is currently serving as an Associate Editor of the IEEE Transactions on VLSI. He was co-recipient of the 2008 ISCAS Best Student Paper Award, the 2017 DATE best IP award, and the ISSCC 2020 Jan van Vessem Award for Outstanding European Paper. He has served as Distinguished Lecturer of the IEEE Solid-State Circuit Society.
About QuTech360 seminars
QuTech360 is a series of seminars for all QuTech divisions where they have the opportunity to build a deep understanding of the topics researched at QuTech. In each seminar, a quantum expert will guide us through one of the main topics studied in their group. For more information, you can contact Grazia Bastasin (g.bastasin@tudelft.nl) |
