As Richard Feynman said: "Nature isn't classical. Decoherence occurs when the quantum behavior of qubits decays. Quantum computing promises to be the next paradigm of computing, harnessing the principles of quantum physics to perform computations and conduct tasks impossible for classical architectures. When measuring a qubit, the result is a probabilistic output of a classical bit. It is further suspected that BQP is a strict superset of P, meaning there are problems that are efficiently solvable by quantum computers that are not efficiently solvable by deterministic classical computers.
