Quantum computing is set to redefine industries such as healthcare, finance, and cybersecurity by utilizing the principles of quantum mechanics. Unlike traditional computers that use bits (0s and 1s), quantum computers work with qubits, which can exist in multiple states at once. This superposition allows quantum systems to process vast numbers of possibilities, offering unprecedented computing power.
What is Quantum Computing?
Quantum computers leverage unique quantum phenomena like superposition and entanglement to perform complex calculations that are impossible for traditional systems. For example, superposition allows qubits to represent multiple states simultaneously, drastically accelerating problem-solving.
