  Quantum computing (QC) holds the promise of revolutionizing problem-solving
by exploiting quantum phenomena like superposition and entanglement. It offers
exponential speed-ups across various domains, from machine learning and
security to drug discovery and optimization. In parallel, quantum encryption
and key distribution have garnered substantial interest, leveraging quantum
engines to enhance cryptographic techniques. Classical cryptography faces
imminent threats from quantum computing, exemplified by Shors algorithms
capacity to breach established encryption schemes. However, quantum circuits
and algorithms, capitalizing on superposition and entanglement, offer
innovative avenues for enhancing security. In this paper we explore
quantum-based hash functions and encryption to fortify data security. Quantum
hash functions and encryption can have numerous potential application cases,
such as password storage, digital signatures, cryptography, anti-tampering etc.
The integration of quantum and classical methods demonstrates potential in
securing data in the era of quantum computing.
