Didier Belot (LETI) has (together Michael Schroeter, Adrien Morel) organised a (virtual) workshop at the International Microwave Symposium (IMS) on 20^th of june 2021 with the title

Cryogenic RF and mmW technology and circuit platforms: a path toward Quantum-Computing

The workshop abstract is

Cryogenic electronics will have a strong impact on our society through applications as Quantum Computing but also, space communication, and high performance computing. Quantum computers, for instance, have the potential to radically advance our computational capability and are predicted to strongly impact fields such as medicine, chemistry, science and finance by allowing to solve computational problems that cannot readily be solved by classical computers. The hardware implementations of quantum computers rely on various quantum bit (qubit) technologies, such as superconducting qubits, spin qubits and Majorana fermions. All of these Qubits require cryogenic temperatures.

There were a total of nine contributions to the workshop and five of these were from the SEQUENCE consortium. The full program is:
