QTREX Quantum

Printed coaxial cryogenic interconnects (in development)

Published by FyncaResearch checked How we research

Where it fits in a quantum computer

Formerly Inspira Technologies, it acquired Nano Dimension’s additively manufactured electronics (AME) and Fabrica product lines on April 6, 2026 and is using them to develop high-density, thermally optimized interconnects for dilution refrigerators. On July 31, 2026 it said its printed coaxial quantum interconnect exceeded RF requirements set by unnamed strategic partners, with transmission from 10 MHz to 20 GHz, at least 68 dB of crosstalk suppression and 4.4 ps average channel skew; on July 1, 2026 it filed a provisional patent on a controlled-conductivity cryogenic microwave interconnect.

What the evidence establishes

Quantum-computing evidence

Positioning: QTREX’s 2026 releases filed with the SEC describe its printed cryogenic interconnect program and partner qualification, without naming a customer.

An explicit quantum-computing product, design-in, supply role, program or partnership, such as a part sold for quantum computers or a named quantum-computer customer. For a maker, it means the company’s own quantum computers or processors. This does not establish revenue, market share, volumes or future sourcing.

Keep in perspective

The quantum interconnect is pre-commercial: partners are unnamed and no quantum order has been disclosed. First-half 2026 revenue was $1.554 million across its AME and medical businesses, and accumulated losses reached $86 million by June 30, 2026.

Specialist business exposure. This describes the breadth or role of the business; it is not an investment rating. A quantum-computing product, design-in or partnership does not by itself establish material quantum revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Coaxial lines

Semi-rigid coaxial cables of stainless steel, copper-nickel or superconducting niobium-titanium, chosen stage by stage to carry microwave signals while conducting little heat.

Scope of the company links: Semi-rigid coax (stainless steel, CuNi, CuBe or superconducting NbTi, often 0.86 mm) carries drive, flux and readout signals between stages. Huber+Suhner is mapped for its quantum-computing semi-rigid range, with NbTi lines under 0.5 dB/m at 4 K and 10 GHz; QuantumCTek sells cryogenic cable assemblies in CuNi, stainless, aluminum and NbTi specified stage by stage; QTREX’s printed coaxial interconnect is still pre-commercial. Much of the market is private: COAX Co. (Japan), TOTOKU (Japan, Carlyle-owned since its 2023 delisting), CryoCoax (an Intelliconnect division), Radiall and Bluefors, which wires its own refrigerators. Furukawa sold its 57% TOTOKU stake in 2022, and Fujikura and Furukawa showed no current quantum coax role in the sources checked.

Flex cables

Flexible ribbons carrying dozens of microwave or DC lines side by side on a thin film, a denser alternative to individual coaxial cables.

Scope of the company links: High-density wiring that carries many lines per cable or ribbon. Printed flex ribbons come from private firms: Delft Circuits’ Cri/oFlex (eight NbTi or silver striplines per 0.3 mm flex with built-in attenuators and filters, sold with Bluefors) and Maybell’s LF CryoTrace, based on an MIT Lincoln Laboratory design it licensed (MIT News, June 2026). Huber+Suhner is mapped for its MXP multicoax system (192 flexible or semi-rigid coax channels on an ISO 100 flange, running to the mixing chamber), Hirose for its SER unit’s NbTi multi-channel coax connector cables and QTREX for printed high-density interconnects in development; these are coax harnesses rather than printed ribbons. Bluefors’ High-Density Wiring (up to 168 lines per port) is private. Rigetti’s 10-K says Quanta Computer may develop flexible cables under a 2025 collaboration, a possibility rather than a disclosed product, so Quanta is not mapped here.
