Overview
QuantWare develops superconducting quantum processors and technologies for manufacturing and packaging them. The company announced a $178 million, or €152 million, Series B on May 5, 2026. Those are two reported currency expressions of one financing, not separate rounds.
Investors included Intel Capital, IQT and ETF Partners, together with returning backers FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures and Graduate Ventures. The company is developing its VIO architecture and KiloFab manufacturing capacity. These plans should not be presented as proof that a 10,000-qubit fault-tolerant computer has been delivered.
Its commercial test is whether customers can integrate reliable processors at scale and whether manufacturing capacity translates into sustainable demand.
Why QuantWare is interesting
Its $178 million Series B finances a supplier model focused on processors, packaging and fabrication rather than only selling a vertically integrated quantum-computing service.
