Abstract

Objectives: To identify the entanglements of arbitrary two-qubit quantum channels and the capabilities to realise quantum teleportation. Methods: The implementation of Schmidt de composition and measurements of quantum system state are equiped in this research. Findings: By constructing the general form of an arbitrary two qubit and measurement state, we able to determine an entanglement of an arbitrary two qubit by utilising Schmidt decomposition. Next, a capability of an arbitrary two qubit entangled state to realise teleportation can be identified by formulating measurement state and unitary operator. Improvement: The methods used in this paper have relatively simple calculations and very beneficial to be implement before developing quantum teleportation system experimentally.
