The brief

Analyst view
  • Says more than half of the world's quantum computing companies use its control systems; $280M raised.
  • OPX1000 (2023) packs 64 outputs and 16 inputs in 3U; linked units aim at 1,000-plus-qubit machines.
  • Sept 2026: first control firm to run an NVIDIA CUDA-Q program across live qubits and GPUs over NVQLink.

Technical approach

As reported
Pulse processor

A classical computer beside the qubits

Its Pulse Processing Unit builds pulses and runs logic in real time, so a measurement can change the next pulse within the same run.

QUA

A programming language for pulses

Experiments are written in QUA at pulse level, or as gates through an OpenQASM 3 compiler, for any qubit type.

GPU link

Qubits wired to supercomputers

NVIDIA's NVQLink ties the controller to GPUs and CPUs; a full qubit-to-processor round trip took about a microsecond in a 2026 demo.
