Photonic quantum computing hits a coherence wall
Phase errors accumulate as photons traverse optical components, destroying quantum coherence after ~50–100 gates and capping computational power across all photonic platforms.
Visibility drops exponentially with circuit depth. Useful limit: ~50–100 gates.
Visibility bounded by ODR interval, independent of total depth. 500–1000+ gates feasible.
No measurement, no feedback, no ancilla qubits. ODR works at room temperature on standard SiN.
Two products, one chip
The same QLT photonic chip architecture powers both a near-term AI accelerator and the full quantum processor.
Photonic AI Accelerator
Matrix-vector multiplication at the speed of light. ODR solves the documented 84% accuracy collapse in large photonic neural networks. Targets the $50B+ AI accelerator market.
Quantum Processor
Universal quantum computation with single-photon inputs. ODR extends coherence for deep quantum circuits. First target: field-deployable defense and intelligence applications — no cryogenics required.

ODR for quantum computing is unpatented territory
Exhaustive searches confirm: no existing global patents combine Optical Distortion Reversal with quantum error correction for photonic qubits. QLT owns this space with 34+ patent filings organized around a product-centered IP moat.
5 patents · ~120 claims
Processor architecture, ODR waveguide, switch, cladding, low-loss circuit.
3 patents · ~60 claims
CV quantum, photonic AI, cryptanalysis.
26 additional filings
ODR lattice method, source integration, memory, qRAM, timing, and more.
Three phases to global-scale quantum manufacturing
Prototype & Strategic IP Fortress
5 strategic seats × $5M each. Pillar 1: $5M split-fab prototype across Ligentec, AIM, imec with encrypted GDS. Pillar 2: $20M IP expansion — 60+ patent families across 7 jurisdictions, defensive litigation reserves, ITAR-compliant infrastructure.
Dedicated Pilot Fabrication Facility
25,000–30,000 sq ft facility with ISO 5–7 cleanroom. DUV stepper, ICP-RIE, PECVD/LPCVD, full metrology. 25–30 FTE. Pilot production: 10–20 wafers/week. First revenue.
Full-Scale Vertically Integrated Fab
50,000+ sq ft purpose-built quantum photonic chip fab. DUV lithography, FOUP automation, lights-out 24/7 manufacturing. 200/300mm wafer class. IPO-ready.
Building a sovereign US quantum chip fab
QLT's capital roadmap scales from a $5M prototype to a $1.2B vertically integrated fabrication facility — capturing federal and state incentives worth $30–70M+ while establishing US-sovereign quantum hardware manufacturing.
- Capital path: $5M → $150M → $1.2B
- Texas OZ: tax-free appreciation on 10-year hold
- JETI Act: 75% school property tax abatement in OZ
- CHIPS Act + TSIF: federal and state grants for US fabs
- Zero state income tax, zero capital gains tax
From the QLT technical team
The electron transistor had 75 years. The photonic switch gets the next 75.
Why QLT's photonic processor is the first credible replacement for the electron transistor since 1947.
ArchitectureWhy ODR inside the chip changes everything
Optical Distortion Reversal as a structural layer — not a lab trick — enables room-temperature quantum.
EnergyAI data centers are burning through the grid. Photonics stops it.
Data centers will consume 980 TWh by 2030. Photonic computing cuts that in half.
The last major platform shift in computing took 75 years. The next one starts now.
QLT is building the first room-temperature quantum photonic processor — a chip that replaces the electron transistor with a photonic switch. If you understand what that means for a $1.8 trillion industry, we should talk.
