Quobly Signs Two Deals to Advance Silicon Qubit Testing
French quantum firm Quobly has signed two memoranda of understanding (MoUs) with Dutch partners this week. The agreements focus on testing and characterization for Quobly’s silicon spin qubit chips. Both documents represent statements of intent. Neither MoU commits funds, sets a product release date, nor reports a qubit count.
Details of Quobly’s Agreements
According to the September 2 press release, Quobly signed an MoU with TNO, the Netherlands Organisation for Applied Scientific Research on that same day. This agreement extends a collaboration initiated in 2025, and continues their joint work on device characterization and materials analysis.
The following day, Quobly signed a second MoU with Orange Quantum Systems, a Delft-based company specializing in automated test equipment for solid-state quantum chips. Both signings took place in Eindhoven as part of a French-Dutch program during President Emmanuel Macron’s visit to the Netherlands.
The primary objective of both agreements is measurement and testing. Quobly develops silicon spin qubit processors on a 300 mm FD-SOI platform, the same wafer type used in commercial chip fabrication. As the company scales its production, it requires efficient methods to assess the performance and variability of each device. TNO and OrangeQS contribute characterization tools to address this challenge, and Quobly provides test wafers, device specifications, and its roadmap.
The use of the term “industrialization” reflects an ambitious goal. Quobly hasn’t publicly disclosed its current qubit count, and neither MoU claims a functional processor. The company’s profile indicates 11 to 50 employees and lists CEA-Leti, STMicroelectronics, and Soitec as partners.
What These Deals Don’t Indicate
An MoU serves as a framework for cooperation; it’s not a contract, a purchase, or a shipped product. Quobly CEO and co-founder Maud Vinet articulated the objective similarly in both statements. Regarding the TNO deal, she stated:
“We are building quantum computers for industrial scale. That means solving the engineering challenges behind the qubit as seriously as we solve the qubit itself. Our cooperation with TNO strengthens this approach by bringing together complementary European expertise in materials, devices and industrialization.”
Developing robust testing infrastructure is a significant bottleneck for any qubit manufacturer aiming for higher device counts. Though addressing this is valuable work, it represents an early stage of development. These two MoUs outline the direction of that work. No performance figures, timelines, or financial terms were disclosed for either agreement.
