Quandela — Photonic Qubits · fobi

Quandela

Quandela manufactures photonic quantum computers and single-photon sources for quantum computing and communication. Quandela raised €50M in Series B funding in 2023 and provides quantum computers to academic and industrial partners. The company is a spinout from CNRS.

The company offers cloud-accessible photonic processors and is a leader in European photonic quantum hardware.

Bull case

Quandela sits at the intersection of two generational opportunities: photonic quantum computing and quantum networking. Its single-photon source technology, spun out from CNRS, gives it a fundamental moat in the hardware stack that few European peers can match. The €50M Series B closed in 2023 shows institutional conviction that the photonic approach — with its natural advantages in room-temperature operation, optical interconnects, and scalability via integrated photonics — can challenge superconducting and trapped-ion architectures. Cloud-accessible processors lower the friction for academic and industrial partners to build on Quandela's stack, creating a flywheel of use-case validation and co-development. The naming of Cyril Dujardin as COO signals a deliberate shift from research-led exploration to operational scaling, exactly the kind of executive depth needed to move beyond prototypes toward commercial deployment. In a European quantum ecosystem that risks fragmentation, Quandela has both the technology and the execution focus to consolidate leadership in photonic quantum computing.

Bear case

Photonic quantum computing has yet to solve its deepest physics problems. Two-qubit gate fidelities lag behind superconducting and trapped-ion competitors, and photon loss at scale remains a fundamental barrier to fault tolerance. Quandela's €50M Series B is dwarfed by the war chests of PsiQuantum (over $1B raised) and IonQ (public market capitalization), which are also placing big bets on photonic and trapped-ion architectures respectively. The company's undisclosed total funding raises questions about burn rate and runway relative to its technical milestones. Meanwhile, IBM and Google are already fielding hundreds of superconducting qubits with roadmaps extending to 2029, and neutral-atom players like QuEra are delivering commercial systems today. The executive restructuring — including a new COO — could as easily signal organizational turbulence as it does maturity. If Quandela cannot demonstrate a credible path to 100+ logical qubits within a defined timeline, it risks being outspent, outperformed, and outmaneuvered by better-capitalized architectures that are already shipping to customers.
