Equation 106 · Part 1 · A Reference Frame Becomes Classical by Publishing Its Orientation

Symbol R_epsilon,delta

Rϵ,δR_{\epsilon,\delta}
Rϵ,δR_{\epsilon,\delta}

What this part means

reported, the calculation must also check whether a non-disturbing classical channel matched to the same fragment marginals reproduces it.

Its job in the formula

ReR_epsilon,delta is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

This proposes an additional falsifier alongside the frame-covariance test: at every parameter point where Rϵ,δR_{\epsilon,\delta} is reported, the calculation must also check whether a non-disturbing classical channel matched to the same fragment marginals reproduces it.

The passage around this formula

…curve to reproduce; its marginal fragment statistics can be copied indefinitely at zero disturbance to the source. This proposes an additional falsifier alongside the frame-covariance test: at every parameter point where Rϵ,δR_{\epsilon,\delta} is reported, the calculation must also check whether a non-disturbing classical channel matched to the same fragment marginals reproduces it. Wherever one does, and the rotor shows no measurable degradation as M grows, the reported number is describing an already-classical…
