Overview

Join to apply for the Security Engineer role at C12 .

C12 develops quantum computers to solve highly complex computing tasks, currently out of reach of even the most powerful supercomputers. Building a quantum computer still needs innovators ready to tackle exciting challenges. C12’s founders are convinced that only a new material for the qubit will bring a technological breakthrough. C12 uniquely uses carbon nanotubes as the fundamental building blocks of its quantum processor. This high-purity material minimises errors, radically improves performance and reduces hardware overhead for fault-tolerant computing. Combined with well-established semiconductor techniques, carbon nanotubes will help scale quantum computing, just as silicon revolutionised classical computing. Our unique & innovative quantum computing technology enables us to address use cases, solving intractable problems our industrial customers are facing.
