Exact target-adapted endpoint transport

Read the clock at the sender before departure. The payload may then be correlated with its classical code $R$ and reference $E$. The theorem applies with $RE$ as the untouched comparison system.

A receiver operation selected by $k$ additionally needs that code. Reserve a two-bit classical register at each route site, copy the classical code along the same causal hops, and apply $M_{k,y}$ only after both payload and code arrive. Copying a diagonal classical register does not clone an unknown quantum state.

The complete received instrument is exactly (eq:instrument), with $X$ relocated. No instantaneous remote classical control is assumed.

For a route of $n$ hops, the ledger is:

With all payload registers reserved initially, the quantum laboratory peak is bounded by

External reference storage is charged separately.

The exact result is for an installed target-adapted chain, not every null endpoint on one previously fixed lattice. En08-B's null-boundary approximation is a different contract CheungEn08.
