t0 provides the Control & Readout System (CRS), a modular microwave platform that delivers precise RF synthesis and digitization up to 10 GHz with up to 4,096 multiplexed channels. The hardware scales from a single 6U board to sub‑rack assemblies of 16 boards and can be expanded to hundreds of units via a full‑mesh backplane, maintaining phase coherence and low‑latency feedback for superconducting sensors, quantum processors, and radio‑astronomy interferometers. An open‑source Linux environment with Python and C++ APIs gives researchers full control over firmware, data processing, and AI/ML integration, reducing system complexity and cost.

Problem
Researchers developing superconducting sensors, quantum processors, and radio interferometers face a lack of scalable, high‑precision microwave control and readout hardware that can grow from a single board to hundreds of units while maintaining phase coherence and low latency.
Solution
t0 offers the Control & Readout System (CRS), a modular microwave platform that delivers precise RF synthesis and digitization up to 10 GHz with up to 4,096 multiplexed channels. The system scales seamlessly from a single 6U board to full sub‑rack assemblies of 16 boards and can be expanded to hundreds of units via a full‑mesh backplane delivering 400 Gbps of inter‑board connectivity. Integrated low‑phase‑noise clock distribution, IRIG‑B timing, and programmable low‑latency feedback enable coherent operation across large arrays of qubits, kinetic inductance detectors, or radio‑astronomy receivers. An open‑source Linux environment with Python and C++ APIs, JupyterLab access, and optional AI/ML integration provides researchers full control over firmware and data processing. The CRS thus consolidates control, readout, and data shuffling into a single, deployment‑ready hardware suite, reducing system complexity and cost for advanced scientific instrumentation.
Target Audience
Primary customers are research laboratories and institutions building large‑scale superconducting sensor arrays, quantum computing hardware, or radio‑astronomy interferometers that require synchronized microwave control and high‑throughput readout.
