SemiQon and Qblox secure €2.5 million EIC Transition funding

SemiQon and Qblox secure €2.5 million EIC Transition funding

The European Innovation Council has approved a €2.5 million grant funding to SemiQon, a leading developer of silicon-based quantum processors and Qblox, a leading provider of scalable and modular qubit control stacks. The goal of the project is to build high quality silicon-based spin-qubits and the tools to control and operate them sustainably, using a scalable quantum computing control stack. The project will be coordinated by SemiQon.

The SCALLOP project aims to tackle two specific challenges: improve qubit quality and reduce the need for cooling by implementing low-charge-noise quantum dots and monolithically integrating a cryo CMOS multiplexer. The envisioned quantum computing architectures rely on the scalable fabrication of qubits, which take advantage from the well-established CMOS technology. The scalable control stack will operate the spin qubits.

By partnering with Qblox, SemiQon aims to accelerate the development of high-quality qubits and quantum processing units. The project allows SemiQon to dedicate more resources to its mission of creating the most scalable, sustainable, and cost-effective quantum processing unit using silicon-based spin qubits. The joint effort with Qblox will simultaneously advance the development of the spin qubit control stack.

“At SemiQon, we are already on track to build the most scalable, sustainable, and cost-effective quantum processors. Through the EIC-funded Transition project, together with our partner Qblox, we will demonstrate the most scalable quantum computer built with SemiQon’s processors,” says Himadri Majumdar, CEO of SemiQon.

Qblox will help SemiQon by characterising their processors in SCALLOP project and in doing so Qblox will further develop its control stacks for spin-qubit based quantum processing units. The modular approach of Qblox’s control stack facilitates scalable control of quantum computing units in a sustainable way. Coupled with SemiQon’s scalable quantum processors, this approach ushers the path for truly scalable quantum computers.

“Qblox is an established player in quantum control, working with many parties around the world to support them in scaling up their quantum processors. In this project, we combine our technology with SemiQon’s expertise in semiconducting quantum devices that embed unique cryo-CMOS multiplexing. Together with our scalable control stack, this will give a quick path to quantum processors that not only push the boundary of the number of qubits but also their quality and consistency,” says Niels Bultink, CEO of Qblox.

Spanning a duration of 30 months, the SCALLOP project will be carried out by a dedicated team from both companies operating across two sites: Espoo, Finland, and Delft, Netherlands. This venture stands as a testament to sustained European funding for early-stage technology development, and it presents a unique opportunity to create the world's most scalable commercial quantum computer. The advancements made through the SCALLOP project are set to surpass global developments in quantum computing, solidifying Europe's leadership in this transformative domain in the long run.
