Quantum cryptography playing a very important role in communication for securing the data over transmission .in this paper describe about quantum computing is more secure compare to traditional cryptography and how quantum cryptography break the traditional cryptography in terms of more security. Some algorithms are described for quantum cryptography like Shor’s algorithm, quantum simulation, Grover’ algorithm etc.
Quantum computing would be able to break the public key cryptosystem in a inconsistent time amount. 1024 bit RSA key is broken using Shor’s algorithm and providing the security over communication. Quantum mechanics concept is used to implement the quantum computing this is more secure way compare to classical computation and speedup.
