The general commuting obstruction

The commuting four-Majorana control › The general commuting obstruction · lines 1821–1831

If a channel is compared in diamond distance to such a control, the resulting statement is a lower bound:

ε_{rec} (N) \geq max {0, 1 - d^{- 1} - d_{⋄} (N, N_{QND})} .

Closeness to a commuting control is not a high-accuracy recovery certificate.
