ChatGPT learns using a formula that was invented in 1847 to calculate the orbits of planets.
w ← w − η∇L
This is gradient descent, and without it, not a single modern neural network would exist. It wasn't invented at OpenAI or Google but in France almost 180 years ago, when the mathematician Augustin-Louis Cauchy was looking for a faster way to calculate the motion of celestial bodies.
Imagine you're standing on a mountain in thick fog. You can't see the bottom, but you can feel the slope under your feet. You take a step where it's steepest downhill, check the slope again, and take another step. Step by step, you end up in the valley.
A neural network does the same thing. The mountain is its mistakes, and the valley is the right answers. Except this mountain doesn't have three dimensions but billions.
Cauchy calculated orbits. His formula taught machines to write.

A research team at TU Wien has uncovered something astonishing: quantum entanglement the mysterious bond connecting particles across space doesn’t form instantly. Instead, it takes about 232 attoseconds (a quintillionth of a second) to fully emerge. Using advanced computer simulations of atoms hit by laser pulses, scientists observed that entanglement develops gradually as one electron escapes and another shifts energy levels, slowly weaving their quantum link through time.
This finding challenges decades of assumptions that entanglement happens outside of time itself. It reveals that even the universe’s fastest phenomena have measurable stages a kind of “quantum heartbeat.”
Researchers now aim to confirm the results experimentally, a daunting task at speeds where light barely crosses a human hair’s width. Cracking these fleeting moments could reshape quantum computing, encryption, and communication, showing that even instant mysteries unfold with rhythm and order.

Overview of Topological Quantum Computing (TQC) with Quantum Knots and Anyons
The concept in @kparrish51’s post (and the linked Reson8-Labs YouTube video) connects early magnetic-core memory (ferrite rings on wires storing bits via magnetization) to modern TQC. In TQC, information is encoded in the topology of braids formed by exotic quasiparticles called non-Abelian anyons (not ordinary bosons or fermions). Braiding their worldlines creates “quantum knots” in 2+1D spacetime; the computation result depends only on the knot topology, not on local details or small perturbations. This makes TQC inherently fault-tolerant at the hardware level.
Magnetic fields enter via physical realizations like the fractional quantum Hall effect (FQHE), where a strong perpendicular B-field in a 2D electron gas (2DEG) creates Landau levels and anyonic excitations. The anyons carry fractional charge and obey non-Abelian statistics—the exchange (braid) applies a unitary matrix to the degenerate ground-state manifold, not just a phase. This stores and processes quantum information robustly, much like magnetized cores but at the quantum-topological level.
The video (tied to work like Layla Hormozi’s talk and the 2024 arXiv paper “Minimal Quantum Circuits for Simulating Fibonacci Anyons”) demonstrates this with the doubled Fibonacci (DFib) model on small qubit lattices—showing fusion, twisting, and braiding in the smallest possible circuits (3–9 qubits). It bridges theory to near-term quantum simulators.
Key Mathematical Foundations (with Equations)
Anyons are defined by fusion rules and braiding statistics. For the simplest universal model (Fibonacci anyons, τ), the fusion rule is: τ × τ = 1 + τ (where 1 is the vacuum). A pair of τ anyons can fuse to vacuum or another τ, creating degeneracy used for qubits. The quantum dimension of τ is the golden ratio (φ = (1 + √5)/2).
Braiding two anyons applies a unitary R-matrix (from the braid group representation). For Fibonacci anyons, the non-trivial braiding phases (in the fusion channels) involve roots of unity tied to the 5th cyclotomic field: R_{ττ}^1 = e^{i 4π / 5}, R_{ττ}^τ = e^{-i 3π / 5} (or equivalent conventions up to global phases; exact matrices are derived from the modular tensor category). Sequences of braids approximate any unitary gate densely in SU(2) (or higher), enabling universal quantum computation by braiding alone.
The full computation corresponds to evaluating knot invariants (e.g., Jones polynomial at a root of unity), which is BQP-complete—hence universal. Worldlines of splitting–braiding–fusing anyons form a knot in spacetime: Computation = braid word ∈ B_n ↦ unitary on fusion space. Local deformations of the braid do not change the result (topological protection).
Research Overview and Key Papers/Journals
• Classic foundational review: Nayak et al. (2008), “Non-Abelian Anyons and Topological Quantum Computation,” Rev. Mod. Phys. (arXiv:0707.1889). Defines anyons, braiding, and fault tolerance. “The unitary transformations remain unchanged under local deformations… serve as logical quantum gates.” Cited >8,900 times.
• Pedagogical Fibonacci focus: Field & Simula (2018), “Introduction to topological quantum computation with non-Abelian anyons,” arXiv:1802.06176. Covers braiding matrices to braid compilation. “Fibonacci anyons… allow for universal quantum computation by particle exchange or braiding alone.”
• Recent theory: Hassler (2024), “Topological Quantum Computing,” arXiv:2410.13547. Emphasizes knots: “The trajectories… form a knot in space-time. The result… does not depend on the concrete form.”
• Universal via double-braiding: Kaufmann et al. (2025), arXiv:2312.16747v2. Shows double-braiding alone suffices in certain SU(2)_k theories.
Newest Technology and Experimental Progress (2024–2025/2026)
Physical Fibonacci anyons remain unrealized in materials, but simulations on quantum processors now demonstrate braiding and universal gates:

NVIDIA just fixed text-to-SQL’s biggest problem!
the release is called Auto Ontology, and it targets the reason an agent can write valid SQL against a company database and still return the wrong number.
the database stores columns, and the agent has to guess what they mean. a column called extendedprice might hold revenue, and two systems in the same company can define revenue differently.
Auto Ontology gives the agent an ontology, a schema that maps business concepts to the columns that hold them and defines how they relate, before any query is written. it drafts that schema from your database metadata instead of making you write it, and a human certifies it.
the ontology holds three things:
→ terms: business concepts like customer, order, or revenue, with descriptions and synonyms, mapped to the exact columns that store them.
→ SQL attributes: reviewed expressions like a margin or a rolling total, reused so every measure is computed the same way each time.
→ relationships: how tables join, including bridge tables, inferred from keys and the data itself.
to draft these, it profiles columns, samples values, extracts terms table by table, and mines past query history for SQL attributes. everything lands in Postgres, with embeddings in pgvector.
at query time, the agent maps the question to certified terms, follows relationships to find the joins, and writes SQL. it checks filter values against the real data, repairs the query if a check fails, and returns the answer with its SQL and steps.
when the data can't support a question, the agent says so. in NVIDIA's demo, a question about return on ad spend on a sales database with no ad data gets a clarifying reply offering revenue instead of an invented number.
so the ontology tells the agent how to compute an answer and also which questions have one at all.
as the architecture in the image shows, an ingestion service compiles the ontology from your source databases, and any agent harness reaches it through MCP, CLI, or REST API. it supports ten engines including Postgres, Snowflake, Databricks, and DuckDB, runs on Nemotron by default or any OpenAI-compatible endpoint, and is Apache 2.0.
check it out on GitHub: github.com/NVIDIA/auto-ontol…
the same principle of defining a schema before the model extracts anything also decides whether agent memory works. I wrote about that in the article quoted below.
