In March 2024, the French Ministry for Armed Forces and Secretary general for investment announced that Quobly would be 1 of 5 startups chosen to be a part of the framework agreement of Proqcima, a program supporting French quantum startups to develop a quantum computer.

Proqcima is a pioneering program that aims to gather the most brilliant minds in the world to tackle the most challenging issues of building fault tolerant large-scale quantum computers. It will involve a 15-year innovation partnership between the government and 5 quantum computing companies with the goal of building two universal fault-tolerant quantum computers of a significant scale:

  • 3-4 years: two logical qubits with a universal set of error corrected gates
  • 6-8 years: running phase estimation with 128 inputs

Quobly wins €2.5 million EIC grant to develop FD-SOI quantum processor demonstrator
July 2023 Quobly wins €2.5 million EIC grant to develop FD-SOI quantum processor demonstrator
The European Innovation Council has approved €2.5 million in EIC Transition funding for Quobly for its MCSQUARE project. This new project will build on the advances made during the Quantum Flagship project QLSI (Quantum Large Scale Integration in Silicon) to deliver an FD-SOI-based quantum processor demonstrator with a novel 4x4 multicore architecture.

This architecture presents several advantages. In the long-term, it will facilitate the distribution of error correction routines over the different cores and support progress towards fault-tolerance. In the short term, multicore architectures can support promising noisy intermediate-scale quantum (NISQ) algorithms, an area where multicore architectures with quantum could provide a real quantum advantage. Quobly systems will be deployed as computational accelerators in HPC centers.

“At Quobly, we are on track to build the most energy-efficient and cost-effective full-stack quantum processor. Through the EIC-funded Transition program, we will demonstrate a multicore architecture leveraging Fully Depleted Silicon on Insulator (FD-SOI) technology, the cornerstone of scaling. We will then be prepared to increase both the number of cores and the number of qubits per core,” said Maud Vinet, CEO of Quobly.
