Domain-specific

• Quantum instrument
  • A quantum instrument is a countably additive operation-valued measure whose value on each outcome event is a completely positive trace-nonincreasing map and whose value on the whole outcome space is trace preserving.
• Quantum Operation
  • Davies and Lewis introduced the instrument precisely as a framework generalizing observables and operations for measurement.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
