This time: qubit fabrication and measurement.
I am excited to share that I just came back from a deep dive in our research facilities, seeing the QuamCore team doing the hard execution work behind our roadmap.
After several years of deep architecture work, QuamCore switched gears at the beginning of 2026: from architecture-first planning into full-stack execution.
This post is about one of the hardest parts of that execution: superconducting qubit fabrication and measurement.
Our team has now established an internal flow to fabricate, package, cool down, and measure superconducting qubits.
The progress in measured energy relaxation time, T1, has been very strong:
January 2026: 43 µs
April 2026: 103 µs
Now: 112 µs
For quantum experts, T1 is only one metric. It is not the full system story. Gate fidelity, yield, repeatability, packaging, calibration stability, and integration with control electronics are all critical.
But achieving T1 = 112 µs from an internally executed fabrication and measurement process is a serious milestone.
For RF and microwave engineers: a superconducting qubit is an extremely sensitive microwave circuit. Every interface matters: dielectric loss, metal surface quality, lithography, Josephson junctions, package modes, filtering, grounding, thermalization, magnetic shielding, and the full cryogenic measurement chain.
One small imperfection can kill the result.
Getting from 43 µs to 112 µs was not magic. It was hundreds of careful steps, failures, measurements, process improvements, and iterations by the team.
To the best of our knowledge, QuamCore is the only Israeli company that has internally fabricated, packaged, cooled down, and measured superconducting qubits - now demonstrating T1 = 112 µs.
This is especially important because QuamCore is not building a standalone qubit experiment. We are building a full-stack superconducting quantum computing architecture, with scalable cryogenic control as a core part of the system.
I am very proud of the QuamCore team.
They are demonstrating not only deep architecture and strategic thinking, but also real execution on one of the hardest paths in quantum hardware.
This is the transition we wanted to see:
From architecture to execution.
From blueprint to hardware.
From strategy to measured results.
More to come.
