Quantum circuits composition for complex protocols: double-direction cyclic controlled teleportation
摘要
Quantum computing is a computational paradigm that has proven efficient in several areas. Despite the progress made in this domain, evolving complex protocols remains a very difficult task. In this paper, we propose to overcome this obstacle by relying on the composition of elementary quantum circuits. The basic idea is to first implement the solution of the same problem for a smaller dimension in the form of a basic protocol. Then, we proceed by combining a set of basic protocols in order to solve the initial problem with necessary adaptations. Our approach is illustrated through elaboration of a double-direction cyclic controlled teleportation protocol. We also show that this protocol allows to provide other functionalities using the same quantum channel. Application examples are presented.
