Qblox
Qblox supplies the electronics and software that generate control pulses and acquire qubit measurements. Its Cluster has configurable modules, low-level Q1ASM programming and a Python scheduling layer, allowing a laboratory to assemble a stack around its experimental needs.

What it does. Where it fits.
Modular quantum control and readout with synchronized programmable electronics
Who should look closer
Hardware teams building or extending quantum experiments that need modular control, readout and accessible pulse-programming tools.
QubitWire’s editorial assessment of practical fit.Explore the control stack
Commercial Cluster hardware is evaluated through Qblox, with product details and documentation available online. Module selection depends on the device and measurement workflow.
Check the current access route ↗What has been demonstrated
Université de Sherbrooke confirms installed Qblox control electronics in its quantum FabLab. Joint work with QphoX and Rigetti demonstrated optical readout of a superconducting qubit; the published study reports 81% single-shot fidelity using a demolition-readout technique.
What remains unresolved
Optical readout is a joint system experiment, with results that cannot be attributed to the controller alone. An 81% demolition-readout demonstration does not establish scalable fault-tolerant operation.
The next question to watch
Can larger customer systems demonstrate reproducible timing, calibration and readout performance as the number of modules and controlled devices increases?
A research question, not a promised milestone.QubitWire coverage
