Noise-Stationary Locking
Regulates an interferometric operating point toward a slope-null condition of a detection-normalized noise objective, reducing first-order jitter-to-noise conversion.
Quantum optics • interferometric sensing • dual-use commercialization
Robust interferometric sensing for the real world, not just the lab bench.
Peterson Quantum Sensing is developing a patent-pending control architecture centered on Noise-Stationary Locking and Phase-Controlled Dark-Mode Injection to improve robustness, suppress jitter-to-noise conversion, and expand the practical field deployment of advanced interferometric systems.
Patent-Pending Core
Filed core control architecture for interferometric sensing and dark-port signaling
Prototype-First
Bench validation, simulation evidence, and a clear path to partner review
Dual-Use Markets
Metrology, LiDAR, navigation, optical links, and other precision sensing platforms
Core platform
The technology is built to tame real-world noise where conventional locks start to wobble.
Band-Limited Objective
Computes a selected-band noise metric and normalizes against optical power, tying regulation to the measurement band that actually matters.
Dark-Mode Injection
Actively uses nominally dark or unused modes as control and signaling channels through known phase-coded auxiliary fields.
Adaptive Control Stack
Supports classical DSP control, coherent recovery, and future ML/RL supervisory extensions for turbulence, drift, and nonstationary environments.
What makes this commercially interesting
Traditional interferometric stabilization usually locks to optical power extrema. In rough terrain, turbulent air, thermal drift, or vibration, that power-optimal point may not be the true noise-optimal point.
The PQS approach instead targets a noise-defined operating point, with the objective of improving robustness under non-ideal operating conditions. That is the kind of distinction that can matter in real hardware, not just on a pretty graph.
In parallel, phase-controlled dark-port injection opens a path to signature recovery, multiplexing, interference rejection, calibration, and ranging using channels that many systems treat as idle.
Application landscape
Designed for programs and markets where precision, robustness, and signal integrity carry real weight.
GPS-Denied PNT
Navigation and timing architectures that benefit from improved interferometric stability and resilience in contested or degraded environments.
Precision Metrology
Surface metrology, vibration-sensitive measurement, optical benchmarking, and industrial sensing workflows where noise performance drives value.
Coherent LiDAR
Potential use in ranging, mutual interference rejection, and coded detection concepts for advanced LiDAR platforms.
FSOC & Secure Links
Free-space optical links and other phase-coded optical architectures that may benefit from turbulence-aware control and dark-mode signaling strategies.
Funding & partnerships
A prototype-first path for grants, lab collaboration, and licensing outreach.
Prototype milestone
The next objective is a benchtop NSL testbed that produces baseline-versus-NSL comparison data, raw traces, and repeatable operating notes suitable for outside review.
Partner fit
PQS is best matched to research labs, strategic collaborators, and companies already working in precision metrology, optical sensing, coherent ranging, navigation, or free-space optical links.
Non-confidential package
Public-facing material is intentionally kept high level. More detailed technical discussion, data review, and application-specific conversations can follow once fit and confidentiality are established.
IP status
Filed core IP, controlled public disclosure, and a clear next-step development path.
Filed core IP
Core architecture filed. The foundational work centers on Noise-Stationary Locking and Phase-Controlled Dark-Mode Injection for interferometric sensing and signal manipulation.
Application-specific filings handled selectively. Public materials describe target markets at a high level without publishing unfiled roadmap details or unnecessary implementation specifics.
Patent-pending posture. Interested parties can discuss licensing, evaluation, or collaboration based on non-confidential materials first, with deeper review available case by case.
Current status
Simulation work underway. Reduced-order control and feasibility models have been used to examine robustness, pilot tradeoffs, and actuator requirements.
Benchtop build in progress. The immediate hardware objective is a practical NSL proof-of-concept using catalog optical components and a closed-loop PZT actuator path.
What PQS is seeking. Thoughtful conversations with labs, licensees, strategic partners, and funding programs that value disciplined prototype evidence over hype.
About
Independent invention, practical engineering, and a bench-first plan to verify the hardware.
Jon Peterson — Founder & Inventor
Jon Peterson is the founder and inventor behind Peterson Quantum Sensing LLC, a Kansas-based venture focused on robust interferometric control and sensing architectures.
His background combines formal engineering training, years of practical design work, and a hands-on approach to building and testing real hardware rather than stopping at theory alone.
PQS is being developed as a prototype-first deep-tech effort: protect the core IP, generate disciplined benchtop evidence, and then engage serious partners in markets where stability, sensitivity, and signal integrity matter.
Based in Kansas, PQS is built around a straightforward idea: make advanced interferometric methods more robust outside ideal laboratory conditions.
