Apex Qubits

About

We are developing superconducting quantum processors — from the design of physical qubits to integrated processor-level systems. The project grew out of decades of experimental physics at CNRS Institut Néel in Grenoble, and is dedicated to turning experimentally validated physical insights into quantum hardware that performs reliably in practice.

Our work addresses a central question in quantum computing: how to build processors whose reliability is inherent to their physical design, rather than maintained through increasingly complex layers of correction and control. By strengthening stability and noise resilience directly at the hardware level, we aim to reduce the operational overhead that stands between serious researchers and the experiments they actually want to run.

We build for research centers and quantum teams who want to own their hardware — not operate a black box. For engineers and scientists with concrete ideas about what they are building, who need a capable, open, well-characterized platform to build on. And for organizations in the civil quantum ecosystem who need enabling technology that actually performs.

Rooted in the pre-maturation program of CNRS, our current efforts focus on refining the processor architecture, verifying key integration steps, and preparing a first processor-level demonstrator.

Progress toward fault-tolerant quantum computing starts with processors that are robust by design. That conviction is the foundation of everything we build.
