About
Qblox is a Dutch quantum control hardware company founded in 2019 as a QuTech spinoff. It develops Cluster modular control stacks, which are hardware-agnostic and support thousands of qubits across multiple qubit types. The company raised a $26M Series A led by Quantonation and Invest-NL Deep Tech and has 146 employees. In February 2025, joint research with QphoX and Rigetti was published in Nature Physics, demonstrating superconducting qubit readout using an optical transducer. In October 2025, Qblox joined the NVIDIA NVQLink program, connecting its Q1 pulse processors to NVIDIA GPUs for low-latency quantum error correction workloads, with deployment confirmed at the Barcelona Supercomputing Center. In November 2025 it partnered with QuantWare and Q-CTRL to launch the Quantum Utility Block (QUB), a pre-integrated superconducting system. Also in November 2025, the DOE announced a partnership with Fermilab to coordinate manufacturing and distribution of the QICK (Quantum Instrumentation Control Kit) open-source platform, and Qblox was selected for DARPA QBI alongside Keysight, Quantum Machines, and Zurich Instruments. In March 2026, Qblox integrated with NVIDIA CUDA-Q via the cudaq-realtime API, achieving microsecond-latency FPGA-to-GPU feedback loops for real-time quantum-classical computing, demonstrated at the NVIDIA GTC conference with Oxford Quantum Circuits. Update 2026-03-17: Qblox is integrating with NVIDIA CUDA-Q to provide a real-time API for low-latency Variational Quantum Algorithms.
