Quantum computing is a rapidly evolving field with the potential to revolutionize various aspects of science, technology, and society. Unlike traditional computers that rely on bits (either 0 or 1), quantum computers harness the principles of quantum mechanics to utilize qubits. These qubits can exist in a superposition of states (both 0 and 1 simultaneously) and exploit entanglement, a phenomenon where linked qubits share a fate regardless of distance. This allows quantum computers to tackle problems that would take classical computers years, if not centuries, to solve.
