QTREX (QTEX) turns 3D insulation to graphene-like carbon for quantum processors

Rhea-AI Filing Summary

QTREX Quantum Ltd. (QTEX) announced a patent-pending technology that uses localized laser processing to directly convert 3D-printed dielectric insulation into electrically conductive, graphene-like carbon, creating patterned conductors without adding separate conductive materials or components. The company is integrating this into quantum packages as monolithic stray-photon absorbers aimed at protecting superconducting quantum processors from harmful radiation.

Research at Northeastern University, using QTREX’s AME platform and DF INSU300 material, produced conductive carbon across 20 laser-processing conditions, with Raman spectroscopy confirming the graphene-like structure. QTREX targets commercial launch of DF INSU300 by the end of the third quarter of 2026 and is validating performance at cryogenic temperatures and high frequencies while collaborating with quantum-computing partners on absorber applications and future integration with superconducting materials.

5 terms

Additively Manufactured Electronics technical

"advancing Additively Manufactured Electronics (“AME”) for quantum computing infrastructure"

Additively manufactured electronics are electronic components and circuits created by layer-by-layer printing techniques instead of traditional machining or assembly. Think of building a cake where each layer can contain wiring, sensors or conductive traces so a finished part can combine structure and electronics in one piece. For investors, this can cut production time and part counts, enable custom or lightweight designs, and open new product opportunities or cost savings across manufacturing and supply chains.

graphene-like carbon technical

"conversion of 3D-printed dielectric material into electrically conductive, graphene-like carbon"

quasiparticles technical

"stray radiation that breaks cooper pairs, generates quasiparticles, shortens qubit lifetimes"

Quasiparticles are collective excitations in solids that behave like particles — for example, a ripple of electrons or vibrations in a crystal that act as if they were a single object. Think of them as a coordinated wave in a crowd that you can treat like one person. They matter to investors because they underlie key technologies (semiconductors, superconductors, quantum devices, sensors) and can affect product performance, patents, and the competitive edge of firms developing advanced materials or electronics.

dilution cryostats technical

"quantum connectivity solutions for dilution cryostats and advancing AME applications"

A dilution cryostat is a laboratory machine that creates extremely low temperatures—thousandths of a degree above absolute zero—by using a special mixture of helium isotopes. Think of it as a super-powerful freezer that lets researchers test and run delicate technologies such as quantum processors and ultra-sensitive sensors. For investors, access to or development of these systems signals involvement in advanced, capital-intensive technologies with long development cycles and potential for high strategic value.

Josephson behavior technical

"configurations designed to explore the proximity effect and Josephson behavior"

A quantum mechanical effect in which paired electrons flow across a very thin barrier between superconductors, producing a measurable current and a precise relationship between voltage and the quantum phase. It underlies devices called Josephson junctions used in superconducting circuits, quantum bits, and ultra-sensitive sensors, so its presence and quality can affect the performance and commercial potential of technologies that depend on superconducting electronics, much like a tiny, frictionless bridge that lets traffic move with special rules.

Exhibit 99.1

QTREX’s Patent-Pending Technology Achieves First Direct Conversion of 3D-Printed Insulation into Graphene-Like Carbon to Protect Quantum Processors

Northeastern University research produced conductive carbon across all 20 tested laser-processing conditions; QTREX targets commercial launch of the underlying dielectric material as DF INSU300 by the end of the third quarter of 2026

Ness Ziona, Israel, August 19, 2026 – QTREX Quantum Ltd. (Nasdaq: QTEX) (“QTREX” or the “Company”) a company focused on advancing Additively Manufactured Electronics (“AME”) for quantum computing infrastructure, today announced a patent-pending technology targeting one of quantum computing’s recognized barriers to scale: stray radiation that breaks cooper pairs, generates quasiparticles, shortens qubit lifetimes and drives up error rates. Using localized laser processing, the technology achieved the first direct conversion of 3D-printed dielectric material into electrically conductive, graphene-like carbon. Selected regions of printed insulation were transformed into patterned conductive structures without added conductive materials or separate component assembly. The printed insulation itself becomes the conductor. QTREX is now integrating this capability into quantum packages as monolithic stray-photon absorbers are designed to intercept harmful photons before they reach superconducting circuits.

Research conducted at Northeastern University, using QTREX’s AME platform and its DF INSU300 dielectric material, produced conductive carbon across all 20 laser-processing conditions tested, and Raman spectroscopy confirmed the carbon’s graphene-like structure. Electrical resistance and conversion depth were controlled through laser power and scan speed, and the study defined a practical manufacturing window balancing electrical performance with the integrity of the printed substrate. This is the difference between producing a material and engineering a component: the results establish a controllable, repeatable process for creating functional carbon structures at chosen locations within printed quantum infrastructure.

As quantum processors scale to higher qubit counts, protection must move closer to sensitive circuitry without adding components or increasing assembly complexity. QTREX has therefore advanced the technology into validation at cryogenic temperatures and high frequencies, measuring the electrical behavior of the laser-written carbon and the absorption response of integrated absorber architectures. The target is photon protection built into printed packages and interconnects rather than attached to them: absorptive structures positioned precisely where circuits are most exposed, designed to replace bulky discrete components, reduce assembly interfaces and reclaim critical space inside the cryostat.

“You cannot assemble your way to a million qubits,” said Dagi Ben-Noon, Chief Executive Officer of QTREX. “QTREX is turning the printed package itself into part of the protection system. The material capability we have established lets us create functional structures exactly where the architecture requires them, close to the most sensitive superconducting circuits. This is the architecture quantum computing needs to scale: protection, connectivity and mechanical structure manufactured as a single integrated system.”

QTREX targets commercial launch of DF INSU300 by the end of the third quarter of 2026, bringing the dielectric material used in the Northeastern University research into the Company’s commercial platform. Results from the cryogenic and high-frequency validation program are expected to follow. The Company is advancing absorber application development with existing industry partners while expanding engagement with additional quantum-computing companies. A subsequent development track will evaluate integration with superconducting materials and electrodes, including configurations designed to explore the proximity effect and Josephson behavior, the junction physics at the heart of today’s leading superconducting quantum processors. Together, these tracks create a path from integrated passive protection to printed quantum components.
