Waterloo, Ontario--(Newsfile Corp. - June 16, 2026) - QuantumCore Ltd. (CSE: QNCR) (FSE: K1Y) ("QuantumCore" or the "Company") is pleased to announce a significant technical breakthrough in the development of its kinetic inductance traveling wave parametric amplifier ("KI-TWPA") platform, achieving performance levels that approach rival existing semiconductor-based amplification technologies. As a result of the recent technical achievements, QuantumCore is accelerating its commercialization timeline. The Company expects to begin shipping evaluation units to select customers under non-disclosure agreements in the coming weeks, enabling integration testing and performance validation within leading quantum computing programs.

The breakthrough addresses one of the most critical infrastructure bottlenecks facing the quantum computing industry as systems scale beyond 1,000 qubits, a milestone expected to be reached across multiple quantum computing architectures beginning in 2027.

Quantum computers operate at temperatures approaching absolute zero, where even small amounts of heat can dramatically impact performance, scalability, and operating costs. Conventional semiconductor amplifiers introduce heat into the cryogenic environment, requiring additional cooling capacity and limiting system density. QuantumCore's superconducting KI-TWPA technology provides high-performance signal amplification while dissipating a fraction of the power consumed by semiconductor alternatives.

"This breakthrough marks a major milestone for QuantumCore and validates our strategy of building the critical infrastructure required to scale quantum computing," said Eugene Profis, Chairman and Chief Executive Officer of QuantumCore. "As quantum processors move beyond 1,000 qubits and toward fault-tolerant systems, heat management and physical space inside cryogenic environments become increasingly important challenges. We believe our KI-TWPA platform is uniquely positioned to address both."

The successful demonstration of the technology also enables QuantumCore to begin formal engagement with foundry partners for future volume manufacturing. Discussions are expected to focus on establishing scalable fabrication processes capable of supporting growing demand from quantum computing companies as the industry transitions from research-scale systems to commercial deployment.

"The significance of this achievement extends beyond amplifier performance," said Chris Wilson, Chief Technology Officer of QuantumCore. "Every milliwatt matters inside a dilution refrigerator. By delivering semiconductor-like amplification performance with less heat dissipation, we are helping remove one of the key engineering barriers to scaling quantum computers from hundreds to thousands and ultimately millions of qubits. Equally important, the performance we are seeing provides a pathway toward foundry-based manufacturing and commercial deployment."

The Company will continue to invest aggressively in research and development focused on integrating additional critical infrastructure functions directly into the amplifier platform. As quantum computers scale to tens of thousands and ultimately millions of qubits, physical space within dilution refrigerators is expected to become increasingly constrained, creating a need for highly integrated cryogenic infrastructure solutions.

"We view this as the beginning, not the end, of our infrastructure roadmap," added Wilson. "Future quantum systems will require tightly integrated cryogenic hardware capable of performing multiple functions while minimizing heat load and space requirements. Our objective is to develop a platform architecture that can address these challenges as the industry scales."

QuantumCore believes its KI-TWPA platform, combined with its growing portfolio of quantum infrastructure technologies, positions the Company to become a key supplier of enabling technologies across the quantum computing ecosystem.

In addition, QuantumCore announces that it has entered into an investor awareness agreement with Altura Media Co. Inc. ("Altura"), a Vancouver, British Columbia-based marketing and communications firm, to provide digital investor awareness and marketing services for a term of twelve months, subject to applicable regulatory approvals. Under the agreement, Altura will develop and execute a comprehensive investor awareness campaign targeting English- and German-speaking investors through a combination of digital advertising, sponsored content, newsletters, videos, and other marketing initiatives designed to increase awareness of QuantumCore and its business. The engagement has a total budget of C$300,000 plus applicable taxes for the twelve-month term. QuantumCore and Altura are unrelated and unaffiliated entities, and, to the knowledge of the Company, Altura does not currently own any securities of QuantumCore. All content and materials produced under the engagement will be subject to the Company's review and approval and will comply with applicable securities laws and Canadian Securities Exchange policies.
