A quantum algorithm is a step-by-step procedure, executed on a quantum computer, designed to solve problems more efficiently than classical algorithms by leveraging quantum phenomena such as superposition and entanglement. These algorithms have the potential to revolutionize fields like cryptography, optimization, and computational chemistry by performing complex calculations at unprecedented speeds.

cryptographic systems

RSA is a widely used public-key cryptosystem that facilitates secure data transmission by using two distinct keys: a public key for encryption and a private key for decryption. Its security is based on the computational difficulty of factoring large integers, making it a cornerstone of modern digital security protocols.

Quantum parallelism is a fundamental feature of quantum computing where a quantum system can simultaneously evaluate multiple possibilities due to superposition. This capability allows quantum computers to solve certain problems exponentially faster than classical computers by processing vast amounts of information in parallel.

quantum parallelism

Quantum entanglement is a phenomenon where particles become interconnected in such a way that the state of one particle instantaneously influences the state of another, regardless of the distance between them. This non-local interaction challenges classical intuitions about separability and locality, and is a cornerstone of quantum mechanics with implications for quantum computing and cryptography.

Quantum Entanglement

Classical algorithms are step-by-step computational procedures that solve problems or perform tasks using a finite sequence of well-defined instructions. They serve as the foundation for computer science, enabling efficient problem-solving across diverse domains by leveraging deterministic processes and mathematical rigor.
