Equation 101 · Part 1 · A Reference Frame Becomes Classical by Publishing Its Orientation
Symbol R_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
psilon,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 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
A fourth rival is more corrosive than the first three because it does not challenge the definitions; it challenges whether they require quantum mechanics at all. Nothing in , , or forces the fragments to be quantum-correlated in a way a classical broadcast could not reproduce. Replace the spin- j rotor with a single classical variable drawn once from the same prior and handed to N independent classical sensors, each corrupted by rotation-equivariant noise…
