Technology Approach

Quantum Machines builds the control layer between classical computers and quantum processors. Their OPX+ controller generates and processes the precise microwave pulses that manipulate qubits, with real-time classical processing capability that’s critical for error correction.

The QUA programming language allows researchers to write quantum experiments that include real-time classical decision-making — essential for adaptive algorithms and error correction protocols where the classical computer must react to quantum measurements within microseconds.

NVIDIA Partnership

The integration with NVIDIA’s NVQLink interconnect is significant: it enables microsecond-feedback loops between GPU supercomputers and quantum processors. This is not optional infrastructure — it’s a prerequisite for practical quantum error correction, where classical decoders must process syndrome data faster than new errors accumulate.

Competitive Position

Strengths: Infrastructure that every quantum computer needs. Hardware-agnostic (works with superconducting, trapped ion, and other modalities). NVIDIA partnership positions them at the centre of the hybrid quantum-classical stack.

Challenges: Zurich Instruments and Keysight also compete in quantum control. Risk that large quantum hardware companies build their own control electronics.
