Aidan LeGrande

I find the structure in problems other people have stopped looking at.

I'm a neurodivergent abstractionist — a pattern-seeker and problem-solver. When something doesn't make sense to me I can't leave it alone; I circle it until its structure turns from noise into something I can hear. One-track mind: a directed-energy weapon, not a shotgun. I don't hand-write code — I think, architect, verify, and direct AI to build. Everything below was built in the last four months.

What I'm chasing

Thought experiment · in progress

The Gadsden Serpent — could 600 mph maglev actually be cheap?

Could the United States have interstate maglev at 600+ mph — the speed that turns coast-to-coast into an afternoon — without the price tag that has killed every serious high-speed proposal here? I worked it from both ends, the physics and the cost. I think there's a path that comes out cheaper, safer, and faster than both today's steel-wheel high-speed rail and the evacuated-tube bet. No vacuum tube.

The vehicle

A maglev "skytram" — elevated, magnetically levitated, zero rolling friction. SR-71-inspired low-drag body plus a flow strategy I call self-organized collapse: shape the wake to settle into a collapsed, low-drag state instead of fighting the air.

The propulsion

Fully electromagnetic and distributed — active coils on every car, no dead weight, so the whole vehicle drives itself. Energy lives onboard in novel sodium batteries, not in a continuous wayside power plant.

The guideway

Because propulsion rides the vehicle, the guideway stays cheap and passive — and powers its own signaling and failsafe loads off waste heat via thermoelectric harvesting (50–150 MW continuous network-wide).

The routes

Drawn in public by slime-mold simulation and quantum optimization — never a consultant's lines. Protected land is encoded as edges the simulation physically cannot cross. Every route traces to a published objective function.

State — honest: a feasibility thought experiment, not a built thing. Solid: the self-powering guideway and the sodium-cell chemistry (already verified in my physics sim). The open core is energy — holding 600 mph against open-air drag is a power problem, and that's exactly the work I'd want real resources behind. I'd rather show you the open problem than pretend it's closed.

Novel findings

Where something is proven, I say proven; where it's a hunch, I say hunch. I verify before I believe — usually to the last digit a computer can hold.

The LeGrandean theorems

quantum information · verified
A small family of exact rules in how structured quantum states come apart. Three are identities. One — a doubling rule — I proved directly and verified to ~10⁻¹⁵, machine precision. Another result overturned an assumption I'd carried: the standard entangler isn't optimal, and the advantage of the better one grows with system size. I think the framework connects to training and running AI models more cheaply, and I have one working data point.

TKFQC

topological QC · theory + sim
A quantum-computer architecture built on a foam lattice — the geometry soap bubbles settle into — that appears to delete magic-state distillation, the single most expensive step in fault-tolerant quantum computing. My simulator suggests a 10–80× reduction in spacetime cost versus the standard approach. A physical device is gated on two hard problems I've stated honestly rather than hand-waved.

Laedere

physics · early
A particle-collider simulator, fed by the same quantum engine. Early, but already doing real physics — not stub code.

What I've built

~465,000 lines of original code · all of it built in the last four months · almost all Rust · solo, AI-leveraged

quanta

Rust · ~101K LoC · active

From-scratch quantum-circuit simulator: 20 crates, 7 backends, 824 tests. Beats a standard industry simulator 3.8–7.8× at high precision.

moire

Rust · ~99K LoC · active

A language model built on quantum interference (the Born rule) instead of softmax. Runs on quanta.

vivarium + terrarium + aether

Rust · ~49K LoC · active

A runtime you can edit while it runs, plus a 3D engine and a verification-first physics sim built on top of it.

proteus

Rust · ~53K LoC · near launch

A Mac-native virtual-machine manager that boots Linux or Windows in ~2 seconds. Homebrew-distributed.

rustfusion

Rust · ~13K LoC · active

The Windows games API, rebuilt clean-room in safe Rust under a five-tier unsafe-code discipline.

rosetta-rust-lens + cargo-tier

method + tool

A disciplined way to translate C/asm/shell into safe Rust — proven on 19 real ports, distilled into 511 rules, turned into a tool others can run.

tkfqc

Rust · theory + sim

A topological quantum-computer architecture on a foam lattice that appears to delete the most expensive step in fault tolerance (~10–80× cheaper).

THE FIFTH + two commercial sites

shipped + maintained

A 4-player co-op horror game (first phase shipped) and two live, revenue-bearing Cloudflare sites I build and maintain. I finish things.

How I work

One problem at a time, all the way to the bottom. Split my attention across five tasks and you'll get five mediocre ones. Give me a single hard problem that actually matters and room to disappear into it, and I'll come back with something nobody expected.

I'm not the right person for everything, and I'd tell you so. I'm the right person for the one thing nobody can quite crack and everybody has started walking past.

If you have a problem like that, I'd like to hear it.

I'm looking for the arrangement that gets the most out of a mind like mine: paid to do the work, pointed in a direction, given the resources — and then left to do what I do best.
