Technology Approach
OQC uses a proprietary Coaxmon architecture — a variation on superconducting qubits where control circuitry is placed in a separate 3D layer above the qubit plane. This reduces interference between qubits and control lines, a key bottleneck in scaling superconducting quantum processors.
The newer Dimon dual-rail architecture aims to combine the speed of superconducting with improved error resilience, bridging the gap toward fault tolerance.
Global Presence
OQC has deployed quantum systems across four continents — London, Tokyo, New York, and Spain — and launched the UK’s first quantum error correction testbed. The company is one of only a handful of quantum hardware makers operating commercially outside the US.
Competitive Position
Strengths: Unique architectural approach (Coaxmon), global deployment footprint, strong UK government and defence connections.
Challenges: Competing against IBM, Google, and Rigetti with significantly less funding. Superconducting is a crowded modality.
