01
Multi-material deposition
Conductive traces and insulating layers built simultaneously, creating functional circuits in geometries no other process can achieve.
Making Quantum Computing Possible
QTREX designs and manufactures the cryogenic interconnect systems that quantum computers depend on to operate. Our technology is focused on advanced manufacturing, materials science, and quantum engineering.

What works in theory does not work in practice
Today
Hand-assembled wiring
Quantum systems are wired by hand - coaxial cables routed one at a time through cryogenic stages. Each cable adds thermal load. Each connection is a potential point of failure.
QTREX
Integrated interconnects
As systems scale to thousands of qubits, hand-wiring hits a physical limit. QTREX manufactures clean, parallel signal paths as a single unit - every trace precisely routed and tested.
Why it's so hard
Every signal must survive the extreme cryogenic environment
A quantum processor operates at 20 millikelvin - colder than outer space. To reach it, interconnects must pass through five distinct cooling stages, each with tighter constraints than the last.

What we build
Cryogenic interconnects, manufactured at scale
QTREX replaces hand-assembled coaxial wiring with precision-manufactured interconnect systems, fully engineered for cryogenic operation.

02
Cryogenic-native design
Every structure is engineered from the ground up for cryogenic operation - not adapted from room-temperature technology.
03
Manufactured, not assembled
Specification-driven production that eliminates hand-assembly. Repeatable. Testable. Scalable.
Better qubits alone won't scale quantum computing. Better connectivity will.
We build the technology that makes quantum systems work.
