Classical Bits and Gates

Traditional computers are approaching their physical limits as transistors shrink to the size of a few atoms, leading to issues like quantum tunneling.

Unlike classical computers that use bits, quantum computers use qubits, which can exist in a state of superposition, allowing them to represent multiple values simultaneously.

Quantum computers can perform complex calculations much faster than classical computers by exploiting superposition and entanglement, but the final result is probabilistic and may require verification.
