The resource and error ledger

All route registers may be reserved before clock readout. The clock uses two qubits. The receiver probe qubit is allocated only after the clock has been consumed. Hence the laboratory quantum peak is at most

The copied classical code costs at most $2(n+1)$ retained bits, and the binary probe outcome adds one bit. An $r_E$-qubit untouched reference is recorded in a separate external-storage ledger.

The smooth classical fields, catalogue, exact gate parameters, locations, and schedule are preinstalled model data. This ledger does not price the acquisition of a continuum classical solution or the physical synthesis of exact real rotations.

For compatible implemented channels, the half-diamond convention is

If input and output comparisons have errors ${ϵ}_{\mathrm{in}},{ϵ}_{\mathrm{out}}$, and the complete tick errors are ${ϵ}_j$, then

Replace one factor at a time and use contraction under channel composition. This is a conditional implementation estimate, not a reported error measurement Watrous.
