Our vision

To power the next revolution in computing by reimagining how quantum hardware is built.

OUR STORY
Cryostat
OUR APPROACH

Quantum computing has
the potential to change our lives.

But frequent errors limit the technology’s viability. We are tackling the fundamental issue: the nature of the hardware itself. We are tapping into the simplest material–carbon–to drive a technological breakthrough in the field.

Application
Our TECHNOLOGY
Unlike other quantum computers, we use carbon nanotubes as the fundamental building block of our processor. By combining the power of an ultra-pure material with an easy-to-manufacture semiconductor device, we are building a scalable platform for quantum computing.

Silicon enabled the emergence of classical computing... it’s time for carbon to do the same for quantum.
