## Cryptography:(Quantum computing new applications)

Quantum computing has the potential to break some of the cryptographic systems that are currently in use, including RSA and elliptic curve cryptography. However, quantum computing can also be used to create new cryptographic systems that are more secure, now we will see more on quantum computing new applications.

Cryptography is the practice of securing information by converting it into a form that is difficult to read without the correct key or password. It is essential for protecting sensitive information such as financial transactions, personal data, and government secrets.

Classical cryptography methods rely on mathematical algorithms to scramble information into a secret code, but these methods can be vulnerable to attacks by hackers with powerful computing resources. Quantum computing, however, has the potential to break some of the most commonly used classical cryptographic algorithms by using quantum algorithms that can efficiently solve problems that are too difficult for classical computers.

One example of Quantum computing new applications of a vulnerable cryptographic algorithm is the RSA algorithm, which is widely used for encrypting digital communications. The RSA algorithm relies on the difficulty of factoring large numbers, but a quantum computer could factor large numbers efficiently using Shor’s algorithm. This would make it possible to break the encryption and access the encrypted information.

To address this vulnerability, researchers are developing new cryptographic algorithms that are resistant to quantum attacks. One such algorithm is the quantum-resistant elliptic curve cryptography (ECC), which uses elliptic curves to generate keys that are resistant to quantum attacks.

Another approach to quantum-resistant cryptography is post-quantum cryptography (PQC), which refers to cryptographic algorithms that are believed to be secure against quantum attacks. The National Institute of Standards and Technology (NIST) is currently evaluating and standardizing PQC algorithms.

In addition to improving cryptographic security, quantum computing can also be used to develop new cryptographic protocols that leverage the principles of quantum mechanics. For example, quantum key distribution (QKD) is a technique that uses quantum mechanics to securely distribute cryptographic keys between two parties. This technique is more secure than classical cryptographic methods because any attempt to intercept the key would disturb it, alerting the parties involved.

Overall this is the one of the Quantum computing new applications, cryptography is a critical area for research and development in the field of quantum computing.
