Sherbrooke-based Nord Quantique has recently secured two pivotal partnerships, propelling its vision of achieving reliable quantum computing. Known for its focus on error-corrected quantum systems, the company is working to overcome the challenges of creating fault-tolerant quantum computers. Through these collaborations, Nord Quantique aims to ensure a stable, North America-based supply chain for its specialized superconducting microchips, positioning itself as a leader in this complex and emerging field.

Quantum computing is fundamentally different from classical computing, with potential applications that range from pharmaceutical drug discovery to optimizing infrastructure like electrical grids. However, the technology is still in its early stages, with the challenge of building reliable, error-free systems yet to be fully resolved. Unlike traditional computers, quantum computers can process multiple possibilities at once. Michel Pioro-Ladrière, Nord Quantique’s vice president of strategic partnerships, explained in a recent interview that a classical computer would solve a maze by testing paths sequentially, while a quantum computer could evaluate all paths simultaneously, drastically speeding up the process.

These advancements require chips that are unlike any standard computer component. Pioro-Ladrière emphasized, “We’re developing hardware with the correct properties for useful quantum computing. Traditional chips don’t work for us, so we need chips that are robust and reliable for quantum-specific applications.” To produce these, the company has secured partnerships with the MiQro Innovation Collaborative Centre (C2MI) in Bromont, Quebec, and NY CREATES in Albany, New York. Both partnerships are essential for achieving reproducibility and consistency in quantum chip manufacturing—elements crucial for Nord Quantique’s growth.

The C2MI partnership provides Nord Quantique with industrial-grade fabrication for superconducting qubits. The collaborative focus is on developing a superconducting foundry, which doesn’t currently exist at scale in Canada. C2MI will build the infrastructure, while Nord Quantique brings expertise in manufacturing superconducting chips. This setup will be vital for Nord Quantique’s roadmap, which envisions an increase from its current team of 32 to 70 as the company continues to grow. According to Pioro-Ladrière, “We absolutely need a secure supply chain for chips to support our growth.”

The NY CREATES collaboration, on the other hand, will use advanced CMOS manufacturing tools to test and scale up quantum chips, positioning Nord Quantique to access high-precision processes in a controlled environment. Unlike a production facility, NY CREATES is an R&D hub, allowing Nord Quantique to experiment with the best tools available in the semiconductor industry to adapt them to quantum needs. This flexibility is essential, as quantum microchip production demands conditions and processes unique to this emerging technology.

Securing a supply of these complex chips domestically also shields Nord Quantique from potential disruptions tied to international dependencies. Given that semiconductor supply chains are tightly controlled and impacted by geopolitical factors, relying on foreign sources could put the company at risk. Pioro-Ladrière noted, “Quantum microchips aren’t commodities. They’re specialized, and international export controls add uncertainty. Our partnerships with C2MI and NY CREATES secure our access to key resources without these risks.”

This collaboration fits into a broader national strategy. The U.S. and Canadian governments have recently launched initiatives, such as the CHIPS and Science Act and the Northeast Semiconductor Manufacturing Corridor, to bring high-tech manufacturing back to North America. With production concentrated from Manhattan to Montreal, Nord Quantique is among the first quantum companies to tap into this cross-border initiative. Steve La Barbera, Communication Counsel at FTG Media, explained in a recent related release that the deals with C2MI and NY CREATES reduce reliance on overseas suppliers. This alignment with governmental strategies not only secures Nord Quantique’s supply chain but also strengthens Canada’s position in the global quantum race.

Nord Quantique’s unique approach also highlights Sherbrooke’s emergence as a leading quantum hub. The company is a founding member of Espace Quantic 1, a facility dedicated to quantum innovation in the city’s DistriQ quantum zone. The facility hosts researchers and experts from around the world, all drawn by Sherbrooke’s growing reputation in the field. “There’s a constant stream of international delegations visiting the zone,” said Pioro-Ladrière. “People come here to learn how we’ve created such a robust quantum ecosystem.”

Despite the significant advances made by Nord Quantique, Pioro-Ladrière is careful to clarify that quantum computing isn’t about replacing everyday devices like laptops or smartphones. Instead, these machines excel in solving specific types of complex problems. “Quantum computing isn’t an extension of AI [artificial intelligence]; it’s a different paradigm,” he explained. While it could complement AI in specific applications, its strengths lie in tackling challenges that classical and AI computing cannot address, such as molecular modeling or infrastructure optimization.

A critical aspect of quantum computing’s potential impact is its ability to break conventional cryptographic codes. As Pioro-Ladrière explained, once quantum computers reach a certain level of capability, they could theoretically decode passwords and encryption systems that currently secure data worldwide. This prospect has prompted efforts to develop quantum-resistant cybersecurity measures. “There’s an arms race to secure access to this technology,” he noted, underscoring the strategic importance of Nord Quantique’s partnerships in Canada and the U.S. to maintain control over the technology domestically.

Looking ahead, Nord Quantique’s partnerships are part of its strategy to achieve fault-tolerant quantum computing, a milestone no company has yet fully reached. La Barbera noted that Nord Quantique’s roadmap stands out, as even major players like IBM are still navigating this challenge. “There’s a short list of companies with a clear path to fault tolerance and a secure supply of quantum chips, and Nord Quantique is on it,” he said.

As quantum technology advances, Nord Quantique remains committed to securing a future in which Canada has a stake in this transformative technology. “Once we achieve fault-tolerant quantum computing, the potential for humanity is immense,” Pioro-Ladrière concluded. “It’s a monumental undertaking, but we’re driven by the possibility of creating a tool that will fundamentally change industries and improve lives.”
