What is Quantum Computing?

Quantum computing is an advanced computing technology that uses the principles of quantum mechanics to process information. Unlike classical computers, which use bits that exist as either 0 or 1, quantum computers use quantum bits, or qubits, which can exist in multiple states simultaneously through a property known as superposition. Quantum computers also leverage entanglement and interference to perform complex calculations more efficiently than traditional systems. This enables them to solve certain optimization, simulation, cryptography, and machine learning problems that are difficult or impossible for classical computers to handle within a practical timeframe. Although still in the early stages of development, quantum computing has the potential to transform industries such as healthcare, finance, logistics, energy, materials science, and cybersecurity through unprecedented computational capabilities.
