About
We build the world’s most powerful quantum processors

QuantWare launched in July 2021, by quantum computing experts Matt Rijlaarsdam and Dr. Alessandro Bruno as a spin-out from QuTech, a globally-leading quantum computing research institute, part of TU Delft in the Netherlands. Together, they had the singular ambition to accelerate the advent of quantum computers by scaling qubit counts with a 3D architecture, while democratizing hardware thanks to the Open Quantum Architecture approach.



Today, QuantWare is the highest-volume supplier of quantum processor units (QPUs) worldwide, with customers in more than 22 countries. Its unique VIO™ 3D scaling architecture is the only technology that unlocks first KiloQubit then MegaQubit-scale, ultra-high-speed quantum processors, delivering exponentially more performance per Watt per dollar invested. 

We are paving the way for the hyper-scale quantum computers that will solve humanity's greatest challenges.
