With nearly a decade of research propelling us forward, Qubic Technologies is poised to help redefine the quantum computing frontier. Their all-new superconducting amplifier doesn’t use standard Josephson junctions. This groundbreaking device is made of a special niobium-based alloy. Its aim is to improve computational and signal processing capabilities in quantum systems, while fundamentally eliminating energy loss to heat. The company, led by CEO Jérôme Bourassa, plans to introduce its amplifier as a drop-in replacement for conventional semiconductor amplifiers by 2026.
Superconducting microwave amplifiers are key enabling technology in quantum computing because they work efficiently even at temperature as low as few millikelvin. Current designs using Josephson junctions produce too much noise to be placed anywhere close to qubits themselves. Qubic Technologies has created a novel ultra-sensitive amplifier to meet this challenge. It looks to dramatically cut the heat generated by amplifiers, with an astonishing goal of 10,000x.
Advances in Superconducting Technology
Qubic’s superconducting amplifier takes advantage of new waveguides that incorporate superconducting niobium alloy developed at Qbic. This new laser-powered technique is a radical shift from current technologies that mostly rely on Josephson junctions. At Qubic, we’re removing junctions to lower the noise level in our communities. This innovation will dramatically improve the general viability of quantum computing systems.
Highlighting capabilities in superconducting amplifiers, Jérôme Bourassa made the case that cooling is a key enabling factor for novel devices. He noted, “At some point, you reach a breaking point where you don’t have enough cooling power accessible to remove the heat from the amplifiers.” This assertion underscores an important aspect of this tech, that effective heat management is extremely important to achieve the best function.
This significant reduction in heat production not only translates directly to enhanced performance, but allows for innovative new design opportunities with highly compact system architectures. Bourassa stated, “Having the capacity to remove the heat, having the capacity to make your systems more compact is definitely the pathway towards something that is viable in the future, both in terms of power but economically.” In our recent announcement, TechConnect’s vision aligns with the rapidly accelerating quantum technology-led wave. Instead, it prioritizes building targeted solutions that fit seamlessly into current structures.
The Role of Collaboration in Quantum Development
Of course, Qubic Technologies isn’t the only company looking to make waves in quantum computing. The company is deeply engaged with the top technology developers in the industry. Collaboration and Partnership Going forward, partnerships are going to be critical as the industry continues to grow and evolve into more specialized, niche sectors. Janne Lehtinen, Chief Science Officer at SemiQon, noted the shift towards specialization: “You had first the few players who did everything, but then when things started speeding up then this was divided into many specialized sectors.”
And this collaborative spirit exhibits itself in other firms as well. Take, for instance, Delft Circuits, a fast-growing Dutch startup focused on developing the world’s most advanced cryogenic cabling solutions. Daan Kuitenbrouwer, Chief Product Officer at Delft Circuits, described the interconnected nature of these technological advancements: “You get this whole zoo of different functional components that all have to be connected to each other.” This type of collaboration between private sector actors boosts the possibility of creative solutions and speeds up the pace of the industry’s advancement.
The field of quantum computing is changing quickly. Putting all these specialized pieces together will ensure the system works as a whole by maximizing efficiency and effectiveness. Qubic Technologies’ amplifier in particular would be fundamental for such an ecosystem, enabling improved signal processing and lower thermal noise.
Future Outlook for Superconducting Amplifiers
The expected release of Qubic Technologies’ superconducting amplifier in 2026 marks an exciting time for development in the quantum computing industry. This optimistic timeline certainly speaks to the company’s priorities of getting never-before-seen technology to market, but it speaks to fulfilling developers’ urgent needs and challenges.
As companies like SemiQon and Delft Circuits contribute their own innovations, the future landscape of quantum technology appears increasingly promising. Competition between various startups and big tech companies will most definitely create a climate ripe for innovation.
Janne Lehtinen commented on the trend towards specialization in quantum technology: “So you didn’t have to be the best at everything but you took the best from the market. I think this is now starting to happen in quantum as well.” Yet, this positive sentiment reflects a macro-movement in the industry towards working together and sharing expertise.
