A Classical computer uses binary bits to store data and conduct operations, utilizing ones and zeroes. Quantum computers operate on multi-state components known as qubits, which achieve the “superposition” of one and zero while also “entangling” in mixed states. In lay terms, it implies quantum computers can perform things that traditional computers can’t, like analyzing vast quantities of data quicker and modeling water molecules.
