With the decreasing development of the classical computation,quantum computation becomes the increasing hot topic recently.In this paper,the fundamental theory of quantum computation is briefly introduced firstly.Then,we give the state of the art of quantum computation and research principles in this field from two different research directions(quantum algorithms and quantum-inspired algorithms).At last,some trends of quantum computation in the future research are given.Through the review and prospect of the whole field,this paper could give a significant guide for the future development of quantum computation.
An elementary review on principles of qubits and their prospects for quantum computing is provided. Due to its rapid development, quantum computing has attracted considerable attention as a core technology for the next generation and has demonstrated its potential in simulations of exotic materials, molecular structures, and theoretical computer science. To achieve fully error-corrected quantum computers, building a logical qubit from multiple physical qubits is crucial. The number of physical qubits needed depends on their error rates, making error reduction in physical qubits vital. Numerous efforts to reduce errors are ongoing in both existing and emerging quantum systems. Here, the principle and development of qubits, as well as the current status of the field, are reviewed to provide information to researchers from various fields and give insights into this promising technology.
Quantum computing has become a hot topic in recent years. The device that used for quantum computing is Quantum computer. Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers. Classical computers, which include smartphones and laptops, encode information in binary ?bits? that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a quantum bit or qubit. There has been some successful development of quantum computer technology, but a great deal of research and development remains to be done before quantum computers become viable as a mainstream technology, and there are arguments as to why this eventuality can never be achieved. The proposed research is focused on Cyber security-Will quantum Computing break the Cyber security?

The principles of quantum computing were laid out about 15 years ago by computer scientists applying the superposition principle of quantum mechanics to computer operation. Quantum computing has recently become a hot topic in physics, with the recognition that a two-level system can be presented as a quantum bit, or “qubit,” and that an interaction between such systems could lead to the building of quantum gates obeying nonclassical logic.
