Periodic Reporting for period 2 - CrioFlex (Cri/oFlex: The missing link towards large scale quantum computing)

Reporting period: 2021-03-01 to 2022-10-31

Summary of the context and overall objectives of the project

Today, an emergent quantum industry is eager to implement quantum computers that are significantly larger in size then current prototypes. The bleeding edge are now quantum processors having about 50 quantum bits, and the challenge is to pass the 1,000 quantum bit milestone. But this also means a huge amount of communication-channels between those quantum processors in a cryogenic fridge with external control electronics outside these fridges. At present, existing (coax) cabling technologies are inadequate for connecting quantum processors of that size with the outside world. This poses a critical bottleneck for developing large scale quantum computers, and without solving that problem, the quantum revolution will come to a halt.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Delft Circuits is the first company that has developed ultra-thin cabling solutions for the emergent quantum industry. These are high-tech, flexible cables, fully dedicated to microwave frequencies in cryogenic environments. We are selling pre-cursor cabling products to various organisations worldwide since Q1 2019. Our Cri/oFlex® technology allows our customers to build quantum computers requiring many communication channels, since our present technology is already capable of shrinking the footprint significantly. Such reduction in footprint is an essential requirement for paving the way to large scale quantum computing.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

We will develop in this project a solution for integrating microwave and thermal components in a monolithic cabling solution. This is an essential step to further increase the scale of quantum computers towards 1,000 or more quantum bits. We have setup a network of validation and qualification partners which collaborate in the project. Thereby, this project enables us to accelerate our product development significantly, to strengthen the European eco-system of SMEs in quantum industry, and to become an important player in the emergent value chain.
