Firmware is the low-level software embedded in the hardware of a quantum control system that governs its fundamental operation, including signal timing, data routing, FPGA configuration, and communication protocols.
Why it matters. In quantum control electronics, firmware sits between the user-facing software (like the Qblox Scheduler) and the physical hardware. It determines how waveforms are generated, how synchronization is maintained, how feedback decisions are executed, and how data flows through the system. Firmware updates can add new capabilities, improve performance, fix bugs, and adapt the hardware to new quantum computing protocols without requiring changes to the physical electronics. The quality and maturity of the firmware directly affects system reliability, timing determinism, and the range of experiments that can be performed.How it connects. Qblox provides regular firmware updates for the Cluster that add capabilities, improve performance, and maintain compatibility with the evolving Qblox Scheduler software. The combination of FPGA-based hardware with updateable firmware means that Qblox customers benefit from continuous improvements to their control stack without hardware changes.
