Quantum Machines
OPX controllers coordinate the electrical signals, measurements and feedback needed to operate quantum experiments. The OPX1000 combines modular hardware with QUA programming and calibration tools; it is a control layer used with separately supplied quantum devices.

What it does. Where it fits.
Programmable pulse-control and readout electronics with real-time processing
Who should look closer
Quantum hardware laboratories that need coordinated pulse sequences, measurement-driven feedback and automated calibration across an experimental setup.
QubitWire’s editorial assessment of practical fit.Read OPX1000 specifications
Public hardware and programming documentation supports technical evaluation, including a route to request the full specification sheet. Physical control experiments require a controller and compatible laboratory hardware.
Check the current access route ↗What has been demonstrated
Quantum Machines reports 99.5% median two-qubit gate fidelity across 11 couplings of a nine-qubit Rigetti Novera using OPX1000 and QUAlibrate. Separately, a UCLA preprint uses OPX feedback to stabilize a silicon double quantum dot.
What remains unresolved
The Novera result is a vendor-reported system integration result, not a universal controller benchmark. The August 2026 silicon-dot study is a preprint and does not establish large-array performance.
The next question to watch
Can larger independent deployments maintain calibrated performance and predictable feedback timing as qubit count and control-system complexity increase?
A research question, not a promised milestone.QubitWire coverage
