Canadian quantum hardware company Qubic has closed an oversubscribed seed financing round totaling $2.5 million USD ($3.5 million CAD). The investment was led by deep-tech venture firm Two Small Fish Ventures, with participation from UC Investments, Quantacet, and UCeed. A spin-off of both the Institut Quantique and the Institute for Quantum Computing, the company will deploy the capital to accelerate the development of its microwave component portfolio, expand manufacturing throughput, and bring a specialized radio-frequency (RF) quantum sensing platform to market.
Qubic’s core technology addresses a primary hardware bottleneck preventing superconducting quantum computers from scaling up: the thermal and power restrictions of dilution refrigerators. Traditional quantum processors rely on standard semiconductor-based low-noise amplifiers within their cryogenic chambers, which generate substantial heat dissipation and can consume up to half the tight thermal budget of a sub-Kelvin refrigerator. Qubic bypasses this obstacle by engineering Kinetic Inductance Traveling Wave Parametric Amplifiers (KI-TWPAs) that derive their non-linear inductance directly from the superconducting material of the transmission line itself, rather than fragile Josephson junctions. This structural shift yields a robust device capable of boosting microwave readout signals right at the quantum limit while cutting heat dissipation to under 0.1 mW per device.
The seed funding coincides with immediate commercial momentum for Qubic’s signal processing devices, following its first commercial hardware sale to quantum control stack developer Quantum Machines. The two firms are actively studying integration pathways to build Qubic’s ultra-low-noise KI-TWPAs directly into hybrid control systems to optimize multiplexed qubit readouts and minimize cryogenic thermal burdens. Beyond the quantum computing sector, the capital will fund a three-fold expansion of Qubic’s engineering team to accelerate its dual-use defense and aerospace roadmap, utilizing its low-noise amplification core to build advanced remote sensing and stealth communication platforms for threat detection and covert operations.
