Abstract

We propose new sequent calculus systems for orthologic (also
known as minimal quantum logic) which satisfy the cut
elimination property. The first one is a very simple system relying on
the involutive status of negation. The second one incorporates the
notion of focusing (coming from linear logic) to add
constraints on proofs and thus to facilitate proof search. We
demonstrate how to take benefits from the new systems in automatic
proof search for orthologic.
