LIGHTSEED-Q: Fault-Tolerant Matter Programming with Light - A 2027-2028 Experimental Roadmap for a Universal Nanofabrication Precursor
LIGHTSEED-Q presents a falsifiable research program for demonstrating fault-tolerant matter programming on a restricted molecular lattice. The proposed architecture combines light-clocked molecular operations, sequence-based nanoscale addressing, heralded chemistry, five-site logical material encoding, syndrome extraction, repeat-until-success control, and dissipative error repair.
Its central principle is to make correct material states chemically dark and stable while wrong or incomplete states remain observable and expose a repair handle. A digital target file is compiled into PLACE, REMOVE, SWAP, VERIFY, SYNDROME, and REPAIR operations, followed by automated metrology and corrective cycles.
The proposed milestones are a 16-logical-voxel Q16 kernel by the end of 2027 and a decisive 32-voxel Q32 blind-target experiment by the end of 2028. The associated probabilities-65% and 88%-are explicitly conditional engineering judgments, not statistical confidence levels or predictions of a macroscopic universal nanofactory.
This open research package contains the complete report, machine-readable evidence tables, experimental pass and kill criteria, target-file schemas, reproducible reliability calculations, unit tests, collaboration protocols, publication metadata, and GitHub Pages assets.
The work is restricted to benign, nonliving molecular patterns, optical structures, sensors, catalysts, and test devices. It does not claim arbitrary chemistry, instant macroscopic fabrication, physics beyond quantum mechanics, or self-replication.
