Abstract
Living in an age of information explosion, the security and reliability of information exchange is getting more and more important. However, a quantum computer or a powerful computer can be used to decrypt the classical cryptographic techniques. As a result, we have to find a method with better security and relibility for information exchange.
This thesis proposes a flow to build a secure and reliable quantum system for information transmission, using the particular physical properties which are very different from the classical method, and is capable of the information security and reliability that classical world is hard to reach.
Quantum system still have its limitation on the physical implementation. For example, the qubit decoherence problem, we talk about it and propose a possible solution in chapter two [1]. And the alteration of quantum state caused by the outside interference of qubits during qubits transmission, the quantum error-correcting code solution is to be discussed in chapter three [2].After removing of these physical implementation limitations, the quantum algorithm of secure and reliable information transmission is proposed in chapter four [3].
