Unlike traditional computer bits, which can represent either a zero or one, qubits can exist in a “superposition” state and represent both zero and one simultaneously.AdvertisementThis peculiar characteristic, along with quantum entanglement, allows quantum computers to perform certain tasks exponentially faster than even the most powerful supercomputers.AdvertisementSelect VoiceSelect Speed0.8x0.9x1.0x1.1x1.2x1.5x1.75x00:0000:001.00x
