Toronto, Ontario--(Newsfile Corp. - April 20, 2026) - QuantumCore Ltd. (CSE: QNCR) ("QuantumCore" or the "Company"), a developer of cryogenic electronic components for quantum computing systems, announced the continued technical progress in its superconducting amplifier platform, with a focus on traveling-wave parametric amplifiers ("TWPAs") designed for second-stage signal amplification in superconducting quantum computing systems.

QuantumCore is developing specialized hardware intended to address key roadblocks in superconducting quantum systems, particularly signal fidelity and thermal load at cryogenic temperatures. The Company's TWPA architecture is designed to operate within cryogenic quantum computing environments and support scalable qubit readout without introducing excess noise or heat.

The quantum computing sector continues to evolve from a research-driven field into an emerging industrial market. While significant investment has been directed toward quantum processor development, the supporting hardware layer, including cryogenic electronics and amplification chains, remains a critical factor in enabling system scalability.

QuantumCore's strategy is centered on this enabling infrastructure layer. Its components are being designed to integrate with superconducting quantum computing platforms, independent of specific qubit architectures, positioning the Company to support a broad range of system developers.

Technical Progress

The Company reports that its TWPA amplifier program has advanced through iterative design and early-stage validation work, with ongoing efforts focused on performance optimization and system integration with global quantum computing efforts.

TWPAs are a key element in quantum readout chains, providing low-noise amplification of the extremely weak signals generated by qubits. As a second-stage amplifier, QuantumCore's design objective is to preserve signal integrity while minimizing added thermal load within the cryogenic environment.

Key Technical Pillars

Low-Noise Signal Amplification

Development of superconducting TWPA designs aimed at achieving high gain with minimal added noise, supporting improved qubit readout fidelity.

Cryogenic Thermal Efficiency

Circuit architectures designed to reduce heat dissipation within dilution refrigerators, a key constraint in scaling superconducting systems.

Broadband Performance

Amplifier designs targeting wide bandwidth operation to support multiplexed qubit readout in larger-scale quantum processors.

Platform Compatibility

Hardware intended to interface with multiple superconducting quantum computing architectures, enabling potential integration across different system designs.

Management Commentary

"Our focus is on solving practical hardware challenges that emerge as quantum systems scale," said Eugene Profis, Chief Executive Officer of QuantumCore. "Signal amplification in cryogenic environments remains one of the fundamental constraints on scaling in superconducting quantum computing. Our TWPA program is aimed at addressing that constraint with designs that prioritize low noise, thermal efficiency, and system compatibility."

Mr. Profis added: "Across the industry, there is significant focus on quantum processors themselves. Our approach is to develop the underlying components required for those systems to operate at scale. In that sense, we view QuantumCore as part of the 'picks and shovels' layer of the quantum computing ecosystem, focused on enabling infrastructure rather than any single platform."
