The Cluster series control stack incorporates digital pulse processing
and analog excellence to control quantum computers.
A single 19” rack Cluster unit accommodates up to 20 fully integrated modules, providing all functionalities required for qubit control and readout. Each module supports signal input and output across a wide frequency range up to 18.5 GHz and incorporates at least six advanced Q1 sequence processor cores for real‑time operations, combined with state‑of‑the‑art analog circuitry to ensure excellent performance.
Perform bias-tee-free two-qubit gate operation on your superconducting qubits.
Achieve pulse placement with 1 ns resolution for your spin qubits.
Measure Bell states with 20ps timing of your NV center.
Qblox’s proprietary SYNQ and LINQ protocols assure channel synchronicity accuracy and establish a data distribution network for fast, scalable feedback. All the modules in the system act as one solid system through the use of our proprietary SYNQ and LINQ backplane system protocols. Both protocols contribute to more stable and reliable qubit setups needed for quantum computing.
SYNQ protocol guarantees synchronization of all channels, with ps-level jitter and great phase coherence for precise qubit control and the highest fidelities.
LINQ protocol provides fast, scalable feedback within all-to-all connectivity for conditional playback and conditional branching.
Qblox delivers a full‑stack quantum control solution, uniting high‑performance hardware with powerful software. Built to accelerate research breakthroughs and large-scale systems, the Cluster adapts seamlessly as the qubit platform grows. Its integrated control and readout architecture ensures robust, high‑performance operation whether managing 5 qubits, 25 qubits, or scaling toward 1000 and beyond.
“ As we build integrated multimodal quantum data centers and connect quantum processors directly with HPC infrastructures, transparent, low-level hardware control is essential to delivering scalable, hybrid quantum–classical computing environments. Qblox enables this level of hardware control through Q1ASM, giving us at Qilimanjaro the precision and flexibility needed to advance our analog and digital QPUs."
