DATA STATUS NOTICE

Data status — the entries below are compiled from dated, first-party releases and official registers, with the original source linked on every brief. They are not a live news feed, and the site owner has not yet completed an independent line-by-line verification pass. Open a source link before citing a figure.

Editorial note

The company reports 1.2 dB typical insertion loss, 40 dB crosstalk and sub-3 ms reconfiguration on a demonstration vehicle, and says samples are going to selected prospective customers. Those are in-house laboratory measurements on a prototype, not a shipping product specification, and the release ties the work to a $100 million Department of Commerce award finalised in September. For this site the notable shift is commercial: a private quantum company selling into AI infrastructure is a revenue lead, not a funding round.

How this entry was published

The launch entries were compiled from dated first-party releases and official registers at the site owner's request and are explicitly marked as awaiting an independent verification pass. From here on an AI agent can only draft: an editor who has opened the original sources moves an entry through reviewed to published, and anything missing a source or a hand-written bilingual note produces no page at all.
