Describe it (summary)

Current projects:

- ORBITAL, an analytic molecular electronic structure engine for the whole periodic table (80% done).

- STRATOS, an analytic trajectory system that works at all regimes, all altitudes, and all speeds (85% done).

Available online tools:

- CIQS, an analytic quantum circuit compilation pipeline (Mapper, Router, Optimizer)
Benchmarked on IBM Benchpress at 1,000,000 qubits in 96 seconds. Hardware agnostic. Native quDit handling. Ready for production. Free download on GitHub for non-commercial use.

- CIQA, an analytic 1:5 ratio Quantum Error Correction code.
Full Pauli correction on all axes. Ran the full Hayden-Preskill black hole circuit on quantum hardware, published the first data past the Page time. Hardware agnostic. Native quDit handling. Ready for production. Free online version on arcadialab.fr.

- CASIMIR, an analytic QCD phase diagram calculator.
Phase boundary Tc(μB), curvature derivatives, saddle-node terminus, glueball spectrum, beam-energy conversion. Ready for production. Free to use on arcadialab.fr & indexed by INSPIRE-HEP.

- CASCADE, an analytic Turbulence Spectrum calculator.
It returns the energy spectrum E(k), Kolmogorov scale η, second and third-order structure functions, and all cascade scales. Ready for production. Free to use on arcadialab.fr.

- DYNAMO, an analytic MHD plasma analyzer.
It computes Alfvén velocity, magnetic diffusivity, wave modes, stability, transport numbers, and timescales, from eight physical inputs. Ready for production. Free to use on arcadialab.fr.

Other projects:

- ALKM, an Analytic Local Kernel Machine. It processes the full 11M Higgs dataset in 15 minutes at 0.71% accuracy (10M fit, 1M pred), dominates CC18 in overall efficiency against SVM and RF, and runs MNIST in ~60s at 0.98%+.
(still optimizing).

- Advanced systems in superconductivity and standing waves, not meant to be public.
(If anyone at the Binnig and Rohrer Center reads this, I have something you will like)
