Who should look closer
Quantum founders researching specialist investors, and readers mapping the companies and technologies across the quantum supply chain.
QubitWire’s editorial assessment of practical fit.Explore the portfolio
The public portfolio can be filtered by technology sector, geography, funding stage and fund. Investment is selective; portfolio inclusion is not a public product-access offer.
Check the current access route ↗What has been demonstrated
Quantonation reported a completed €220 million second-fund close on 18 February 2026, with 12 investments already made by that fund. Qblox separately confirms Quantonation co-led its completed $26 million Series A in June 2024.
What remains unresolved
Fund size and portfolio breadth establish financing activity, not realized returns, successful commercialization or quantum advantage. The portfolio also includes businesses outside quantum computing.
The next question to watch
Which portfolio companies can document repeatable customer deployment and sustained commercial adoption beyond research partnerships?
A research question, not a promised milestone.QubitWire coverage
