TL;DR
This paper introduces two canonical forms of perfect quantum channels, including GHZ and W states as special cases, along with orthogonal measurement bases, enhancing understanding of perfect quantum teleportation.
Contribution
It presents two new canonical forms of perfect quantum channels, expanding the framework for perfect teleportation beyond previously known states.
Findings
GHZ and W states are special cases of the canonical forms.
Orthogonal measurement bases for these channels are provided.
The forms facilitate perfect teleportation using these states.
Abstract
Recently, Agrawal and Pati [Phys. Rev. A 74, 062320 (2006)] have given a class of W-states that can be used for perfect teleportation. Here, two canonical forms of perfect quantum channel are presented by transformation operator and the GHZ state and the W state are special case of those two canonical forms of perfect quantum channel. Furthermore, the orthogonal complete measurement bases are given.
