t0.technology builds vertically integrated superconducting quantum sensor systems and microwave signal-processing electronics for detecting weak electromagnetic signals across the RF, millimetre-wave, terahertz, and far-infrared bands. We draw on Canadian leadership in large-scale radio instrumentation and experimental astrophysics, including technology heritage from ground- and space-based instruments. Our systems are used by national laboratories, space agencies, and major scientific collaborations in Canada, the United States, and Europe. By combining superconducting sensor design, nanofabrication, cryogenic/microwave integration, and digital readout electronics, we deliver deployable systems for high-value sensing gaps in industrial and government domains.
