Proof of proveit.physics.quantum.circuits.qcircuit_eq theorem

import proveit
theory = proveit.Theory() # the theorem's theory

%proving qcircuit_eq

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
qcircuit_eq:
(see dependencies)

qcircuit_eq may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
