Not rope

Braids and topological quantum computing

Same branch of mathematics. Zero input to a terminal-eye job.

Does not pick a knot

This page does not pick a knot for you. DNA, molecules, quantum braids and vortices stay off Decide.

What it means

Non-Abelian anyons implement gates by braiding. The operation depends on the topology of the braid, not on the exact path — the same idea that a knot type does not care how you wiggle the rope. Evaluating the Jones polynomial is related to this model. That is cousin math. It is not a fishing or dock-line constraint.

What it predicts

·Some proposed quantum gates depend only on braid class.
·The Jones polynomial of a link is a real mathematical object.
·Local wiggling of a world-line does not change the braid class.

What it does not predict

·It does not rank the knots we cover.
·It does not say a Palomar is ‘topologically protected’.
·It does not belong in Decide, Diagnose, or a manufacturer rating.

Not for

·Any fishing or boat knot we cover
·Anything that ranks a knot

This essay is not about a fishing or boat knot we cover.
