Development updates
What’s happening at PQSensing — and the timeline behind it.
A running log of progress: the patent filing, validation milestones, publications, partnerships, and platform work. Faded entries mark major frontier-AI model releases over the same period — a backdrop that shows how the theory, filings, and validation path advanced alongside a fast-moving generation of reasoning tools.Subscribe via RSS.
Brand system, official logo, and in-page catalog player
Adopted the official Peterson Quantum Sensing logo, letterhead, and typography site-wide, gave the Media + Architecture practice its own identity, and embedded an in-page player for the founder's EverSound Records catalog.
Site rebuilt on Astro with interactive NSL + DPI demos
pqsensing.com migrated to a static Astro build: live Noise-Stationary Locking demo with shareable-state URLs and a CSV bench-trace loader, a new dark-port matched-filter demo, typeset math, and a publications index.
AI frontier: Anthropic releases Claude Sonnet 5

Validation path aligned to the Liquid Instruments Moku platform
Targeted the Kansas State prototype at the Liquid Instruments Moku FPGA platform, so a first reproducible bench validation of NSL runs on standard, widely available lab hardware.

Licensing-first commercial and investor outreach
Opened licensing-first conversations with precision-optics makers and deep-tech investors, positioning NSL as a hardware-agnostic supervisory layer that sits above existing PDH and cavity locks rather than replacing them.
Three technical white papers published
Non-confidential papers on Noise-Stationary Locking + Dark-Port Injection, objective-function supervisory control modules, and atom-interferometric extensions are available with BibTeX citations.
Introductory call with Vescent on where NSL fits
Vescent's R&D team took an introductory call on layering Noise-Stationary Locking above the D2-125 and SLICE-OPL laser-servo platforms as a firmware or licensed supervisory module.

Kansas State University to prototype NSL (summer research)
After a Zoom review, Prof. Meng (Ming) Han's group at Kansas State University took on a summer research project to prototype Noise-Stationary Locking, with follow-on discussion toward DPI-assisted delay measurements.
Seeking a validation partner for the tabletop MZI sprint
Actively looking for a university lab, metrology partner, or sponsor to run the first classical Mach-Zehnder comparison of a conventional lock against NSL under controlled disturbance.
Standardized the bench-trace data format (PQS-Trace-v1.0)
The interactive demo now ingests measured (delta, P, N_band) traces directly, so validation-sprint data will map onto the published thesis with zero rework.
USPTO filing receipt — utility application 19/535,045
The USPTO issued the official filing receipt for non-provisional utility application No. 19/535,045, "Noise-Stationary Locking and Phase-Controlled Dark-Port Injection for Interferometric Signal and Noise Manipulation." PQSensing is patent pending.

Prototype-funding path opened
Began outreach for prototype funding to build the first hardware embodiments of NSL and Dark-Port Injection — the actuators, detectors, and phase shifters for a tabletop demonstrator.
