Quantum computers harness the strange laws of quantum mechanics to process information in ways classical computers can’t. Instead of bits, they use qubits, which can be both 0 and 1 at the same time. This allows quantum computers to tackle problems, like factoring huge numbers, with unparalleled speed. Their unique power isn’t just theoretical—it’s what makes them game-changers for fields like cryptography and cybersecurity. Learn more
