Regular transport and record readiness

Choose a straight developed spatial segment of length $\ell >0$ inside the retained convex regular tube. For $n\ge 1$, set

At station $j$ install an equal $p$-qubit payload register $A_j$. Prepare $A_1,\dots ,A_n$ in independent blanks $\omega$, independent of $A_0$ and every reference.

Fix a supplied developed speed parameter $0<\upsilon \le 1$. At hop $j$, apply the permitted tick-boundary SWAP between $A_{j-1}$ and $A_j$, over developed duration

The cross-port dependencies have the specified straight future-causal routes. Same-station dependencies are future timelike.
