RA'ANANA, Israel, April 30, 2026 -- Inspira Technologies OXY B.H.N. Ltd. ("Inspira" or the "Company") today announced the entry into a Joint Development Agreement (the “Agreement”) with Qarakal Quantum Ltd. ("Qarakal Quantum" or “Qarakal”), a full-stack quantum computing company developing superconducting quantum computers. The collaboration brings Inspira's Additively Manufactured Electronics (AME) platform, which operates under the brand name QTREX, into a working superconducting quantum environment to address one of the field's most persistent scaling challenges: high-performance signal connectivity in cryogenic environments.

The Agreement establishes a structured, multi-phase engineering program to test and evaluate Inspira's technology under quantum-relevant cryogenic conditions. Qarakal Quantum will provide the technical requirements for the program, after which the parties will finalize a joint development plan with agreed success metrics, testing scope, timelines, and resource commitments.

Under the joint development plan, Inspira will provide Qarakal Quantum with 3D-printed conductive and insulating structures designed to test high-density routing, integrated transitions, embedded shielding concepts, monolithic rigid-flex structures, and more compact interconnect geometries within constrained cryogenic volumes. Qarakal Quantum will test and integrate these structures at milli-Kelvin temperatures in its cryogenic development environment and provide engineering feedback.

Qarakal’s technology reflects a convergence of advanced academic research, intellectual property and hands-on engineering execution. Qarakal focuses on the design and fabrication of superconducting quantum processors, along with the development of novel quantum gates and circuits aimed at addressing complex computational challenges beyond the practical reach of classical systems.

"This Agreement places Inspira's technology in a real-world quantum development environment, where its performance can be evaluated under relevant cryogenic conditions," said Dagi Ben-Noon, Chief Executive Officer of Inspira. "This is a structured technical collaboration built around to be agreed upon defined metrics, direct cryogenic testing, and engineering feedback. This is how real value is built in quantum infrastructure- through measurable execution against one of the field's most important scaling challenges."

Dr. Nissan Maskil, Chief Executive Officer of Qarakal Quantum, added: “At Qarakal, our mission is to move quantum computing beyond monolithic lab machines toward modular, deployable, and scalable quantum infrastructure. A critical bottleneck in this evolution is the cabling density and thermal efficiency required to manage scaling signal connectivity within the dilution refrigerator.”

This collaboration marks a concrete step in Inspira’s strategic expansion into quantum computing and reinforces the Company’s focus on addressing one of the field’s most important infrastructure bottlenecks: high-performance connectivity within cryogenic environments for superconducting systems.
