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.
