Destructive clock readout

Finite compression and the complete Enter interface › Destructive clock readout · lines 1829–1841

The instrument is implementable in the admitted finite gate model using one fresh probe qubit and the isometry

ψ ⟼ y = \pm 1 \sum ∣ y ⟩ \otimes M_{k, y} ψ .

Completeness makes this an isometry, which extends to a finite unitary. Destructive probe readout gives the printed instrument. This is an exact abstract gate construction, not a hardware synthesis certificate.
