Some Applications of Quantum Information Theory

The need for security has been gradually increasing in the era of technology. Secure and solid trade of data between gadgets is vital for any organization in the ongoing computerized world. Cryptographic strategies are utilized to guarantee the protected transmission of information, guaranteeing the client's security by putting away and communicating information in a specific organization. Utilizing encryption, just the expected client having the key can get to the data. During information or on the other hand fundamental transmission, the channel ought to be gotten by utilizing vigorous encryption methods. This paper helps us to understand the mechanism of Shor's algorithm in a simple manner. The initial part of the paper gives us a quick introduction about the unitary gates used. The paper further explains about the importance of the estimation of quantum phase estimation along with quantum Fourier transform. It is also utilized to reduce factorization problem to order finding problem. This paper contains detailed explanation about factoring a number using shors algorithm.
