Domain-specific

• Quantum Operation
  • Pechukas showed that when system and reservoir begin correlated, a reduced map can be defined only on a restricted compatibility domain and its linear extension to all system states need not be positive or CP.
• Reduced Dynamics
  • Pechukas proved that correlated initial conditions can restrict the physically meaningful domain and can yield extensions that are not positive, much less completely positive.

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.
