Subspace-aperture transporter

The subspace-aperture transporter was a variant of transporter technology in the Federation. It apparently was first implemented in the 2420s.

The technology utilized wormholes in some manner. Dr. Thomas Alden wondered if it was as disconcerting as "having one's molecules scrambled about," just before he was subject to it on a mission. (Star Trek: Phoenix: "Cloak and Dagger")
