Canadian quantum hardware company Qubic has successfully raised $2.5 million USD in an oversubscribed seed round led by Two Small Fish Ventures, with contributions from investors like UC Investments, Quantacet, and UCeed. This funding will help Qubic enhance its microwave component offerings, boost manufacturing capacity, and introduce a specialized radio-frequency quantum sensing platform to the market.
Qubic’s innovative technology targets a significant challenge in scaling superconducting quantum computers: the thermal and power limitations of dilution refrigerators. Unlike traditional semiconductor-based amplifiers that generate excessive heat, Qubic’s Kinetic Inductance Traveling Wave Parametric Amplifiers (KI-TWPAs) leverage the superconducting material of the transmission line for non-linear inductance, reducing heat dissipation significantly. These amplifiers enhance microwave readout signals while maintaining minimal heat output.
The funding comes as Qubic gains commercial traction, highlighted by its first hardware sale to Quantum Machines. The two companies are exploring ways to integrate Qubic’s amplifiers into hybrid control systems to improve qubit readouts and reduce cryogenic thermal loads. Additionally, the investment will support the expansion of Qubic’s engineering team, advancing its plans in defense and aerospace sectors to develop remote sensing and stealth communication technologies.
