QuantWare raises €20 million Series A to power the world's largest quantum computers

Delft, Netherlands -- March 4, 2025 -- QuantWare, the quantum computing company building technology to create the world’s most powerful quantum processors, has raised a €20 million Series A round.

The round was co-led by Invest-NL Deep Tech Fund and Innovation Quarter, with participation from EIC Fund and existing investors including FORWARD.one, Graduate Entrepreneur Fund and QDNL Participations, as well as Job van der Voort, founder and CEO of Remote.com

QuantWare develops VIO, a technology that allows its customers to create the world's largest quantum processors (QPUs). VIO solves the scaling bottlenecks that limit the size of QPUs today, allowing users to scale any qubit design and unlocking the fastest path towards quantum computers with more than 1 million qubits in a single processor.

Without VIO, quantum processors are limited in their number of qubits and computer builders need to resort to networking together many smaller systems to build a single large system. Due to the noise introduced by these network links, they will be exponentially less powerful than a monolithic large system. While the quantum computers of players like Google and IBM have 100 to around 1,000 qubits, QuantWare’s technology will allow the industry to move towards far more powerful and capable quantum computers.

With best-in-industry fabrication capabilities, QuantWare offers VIO via its own designed QPUs, while third-party customers can make use of the technology via Foundry and Packaging Services.

QuantWare already powers quantum computers for customers in 20 countries around the world.

The new funding will be used to further develop VIO and build out its chip fabrication facilities. This will allow QuantWare to prepare VIO to enable the creation of much larger QPUs and deliver its technology to more customers - answering the increased demand of its global customer base.

‍“Our mission is to make VIO the scaling standard, and have it power the first million-qubit quantum computers of the hyperscalers of tomorrow. ” said Matthijs Rijlaarsdam, CEO and co-founder at QuantWare. “We are building the best team in the world to achieve this mission. Accelerating the path towards that moment is a very important thing to do, as systems of that size will change the world”

Contralto-A: a QPU for quantum error correction

Last week, QuantWare announced the launch of pre-orders of ‘Contralto -A’, a QPU made for error correction. Following the recent announcement of Google’s ‘Willow’ error-correcting quantum chip, QuantWare has seen a surge in demand for customers looking to achieve a competitive roadmap towards large scale error correction.

Contralto-A is intended as a first step on such a roadmap and is designed to be easily upgradable to QuantWare’s larger VIO-powered QPUs. It is almost twice as large as competing solutions that are commercially available.
