The core difference between quantum computing and classical computing is that classical computing is based on classical bits, while quantum computing is based on quantum bits. With the development of Moore's Law, the chip scale of classical computing continues to decrease, and the quantum tunneling effect cannot be ignored. In the future development of computers, either quantum properties should be overcome and continue to be used to promote classical computing; Either actively embrace the characteristics of quantum physics and directly utilize quantum effects for information processing from the perspective of quantum computing.

Classical bits can only exist in one or two states, while quantum bits exist in the form of sum superposition and can handle computational problems of ultra large scale data through effects such as quantum superposition and entanglement. The evolution of the 01 qubit state corresponds to the rotation of the state vector on the Bloch sphere. In theory, a quantum computer with hundreds of qubits can handle more computation simultaneously than the number of atoms in the known universe.
