Understanding Quantum Computing

Quantum computing relies on the principles of quantum physics, which allows information to exist in multiple states simultaneously. Traditional computers process information as bits, represented as zeros and ones, but quantum computers utilize quantum bits or qubits, which can be both zero and one at the same time due to a phenomenon known as superposition. This unique property enables quantum computers to perform complex calculations at unprecedented speeds by processing vast amounts of data simultaneously rather than sequentially. As a result, quantum computing has the potential to revolutionize industries by solving problems that are currently impractical for classical computers.
