Qblox Tech Stack

Quantum control electronics for scaling qubit systems

Technology, Information and Internet Delft, South Holland 51–200 employees Founded 2018 Privately Held

Qblox manufactures proprietary control stacks—the hardware and firmware layer that bridges classical compute and quantum processors. The tech stack is deeply embedded: FPGA toolchains (Vivado, Quartus), hardware description languages (VHDL, Verilog), and low-level control software (Python, C/C++, LLVM/MLIR). Active hiring leans 68% engineering with senior and lead-level density, paired with simultaneous scaling of sales, marketing, and GTM functions—typical of a hardware-software hybrid moving from research spinoff into commercial deployment.

About Qblox

Qblox designs and manufactures quantum control stacks that interface between classical control electronics and quantum processors. The product is sold to quantum computing research teams, national labs, and HPC centers integrating quantum co-processors. Founded in 2018 as a spinoff from QuTech (a quantum research institute in the Netherlands), the company operates across three parallel tracks: refining the core control hardware (high-speed PCB design, FPGA synthesis), scaling software capability (CI/CD for embedded systems, modern tooling adoption), and establishing commercial presence (demand generation, regional go-to-market). Current architectural limits—noise performance, drift stability, and qubit count scaling—shape engineering priorities.
