A quantum computer's qubits operate at temperatures colder than outer space. The signals they produce are so faint that getting them to room temperature without destroying them is an engineering problem that nobody outside the field thinks about — until now. QuantumCore, a startup spun out of the Institute for Quantum Computing at the University of Waterloo, has secured up to $1.7 million in non-dilutive funding from NSERC, the Canadian research council, to accelerate development of a component it says is becoming the Achilles heel of the industry: the low-noise amplifier that sits at the edge of the quantum refrigerator, lifting qubit readout signals from near-silence to something warm electronics can process.

The grant, announced April 23, builds on a larger funding story. QuantumCore has raised $10.7 million in dilutive and non-dilutive financing since launching roughly six months ago, closed two private rounds totaling $9 million since October 2025, and listed on the Canadian Securities Exchange earlier this month. Waterloo institutional news The company was co-founded by Christopher Wilson, a professor of electrical and computer engineering at Waterloo who serves as chief technology officer, and Eugene Profis, chief executive. Wilson's lab and the university's Quantum-Nano Fabrication and Characterization Facility are part of what QuantumCore is buying with this deal. Newsfile Corp. release
The component at the center of the work is called a traveling-wave parametric amplifier, or TWPA. Superconducting quantum computers — the leading hardware approach at Google, IBM, and most other major players — rely on qubits that must be kept within a fraction of a degree of absolute zero. When a qubit measures its own state, it produces a radio-frequency signal at tens of gigahertz. That signal must travel from the bottom of the dilution refrigerator, where temperatures hover around 15 millikelvin, through coaxial cables to amplifiers at the next temperature stage and eventually to room-temperature electronics that convert it to a digital readout.

The problem is noise. Every amplifier in that chain adds a small amount of electronic noise. Get the math wrong and you degrade the qubit fidelity — the probability that a measurement correctly reads a zero or a one. In early machines with dozens of qubits, that noise was manageable. As companies push toward hundreds and thousands of qubits, the readout chain has become a scaling bottleneck. QuantumCore is building a superconducting TWPA it says can amplify those faint signals with minimal added noise, sitting right at the qubit stage inside the refrigerator where the signal is most vulnerable.

"It's a necessary product for quantum computing companies that are just a few years away from launching computers with thousands of qubits," Wilson said. Waterloo institutional news The company describes its hardware as addressing qubit communication, stability, and scaling — not the processor itself, but the infrastructure around it.

The picks-and-shovels framing is deliberate. QuantumCore is not pitching a better qubit, a faster algorithm, or a novel error correction scheme. It is building one layer of the support stack that every superconducting quantum computer requires: the first amplifier in a chain that runs from millikelvin temperatures to the digitizer on your bench. Five full-time technical employees are executing that plan. Waterloo institutional news
Whether the NSERC grant accelerates anything material depends on how quickly the TWPA prototype matures and whether it clears the noise floor that commercial customers require. QuantumCore lists its product as aimed at operators launching machines with thousands of qubits in a few years. That timeline tracks with what Google and IBM have said publicly about their own roadmaps. The grant is non-dilutive — Canadian government money, not equity — which means the company's existing shareholders did not get diluted. The CSE listing six months after launch is unusual velocity for a quantum hardware startup, and the terms of that listing have not been disclosed in detail. Waterloo institutional news
The NSERC Alliance Quantum program, which backed this project, has funded several quantum infrastructure proposals at Canadian universities. Waterloo says QuantumCore is its third major IQC spin-out in recent years. The question for this particular spin-out is whether the TWPA it is building hits the noise specification that the thousands-of-qubits crowd actually needs — and whether it can get there before the big players decide to build their own amplifiers in-house.
