Quantum Computing

Guides

Quantum computing is a revolutionary subfield of computer science that leverages principles from quantum mechanics to process information in fundamentally new ways. Unlike classical computers that use bits representing either 0 or 1, quantum computers use quantum bits, or qubits, which can exist in a superposition of both states simultaneously. This property, combined with another quantum phenomenon called entanglement, allows quantum computers to perform a massive number of calculations in parallel, giving them the potential to solve certain complex problems—such as in drug discovery, materials science, and cryptography—that are intractable for even the most powerful classical supercomputers.

Quantum Information Science (QIS) is an interdisciplinary field that merges principles from quantum mechanics with computer science and information theory to explore how information can be acquired, processed, and transmitted using quantum systems. It investigates the fundamental capabilities and limitations of information processing by harnessing uniquely quantum phenomena like superposition and entanglement, where a quantum bit (qubit) can exist in multiple states at once or be intrinsically linked to another, regardless of distance. While quantum computing is its most prominent application, QIS also encompasses the development of ultra-secure quantum communication networks, advanced quantum sensing for precision measurement, and the theoretical foundations that underpin these revolutionary technologies.
