The rise of quantum computing brings both chances and challenges to today's digital systems, especially in areas like IT services and financial systems. Current encryption methods, like RSA, ECC, and Diffie-Hellman, could be cracked by quantum computing techniques such as Shor’s and Grover’s algorithms. This paper looks at how Post-Quantum Cryptography (PQC) can help keep systems safe and strong in a world where quantum computing is becoming more real. It examines recent progress in different types of cryptographic methods, including lattice-based, code-based, multivariate polynomial, and hash-based approaches. The study shows how PQC can be used in important financial platforms and IT environments. The results show that even though PQC uses more computer power, it's essential to protect important transactions, digital identities, and long-term data safety from quantum threats. The paper stresses the need to use PQC standards, like those from NIST, to make sure digital systems stay secure in the future.
