Quobly
Quobly is a pioneer in the development of a fault-tolerant quantum computer based on semiconductor qubits. With a breakthrough method, Quobly addresses both techno-scientific challenges as well as industrial production, paving the way for mass production of the millions of qubits essential for practical, large-scale quantum computers. Based in Grenoble, the startup is the result of 15 years of collaborative research between internationally recognized RTOs, CEA Leti and CNRS. Founded in 2022, Quobly has brought together a team of experts from the semiconductor industry and distinguished researchers in quantum technologies. In 2023, Quobly made headlines with a seed round of 19 million euros, establishing a new record for seed funding of a European startup in the quantum sector. Today, Quobly employs 25 people.
