Martomeu Bonserrat, or Quantonio to his friends, is a researcher determined to discover and unravel the secrets of quantum computing. Believing himself superior to no one, he builds with his own hands the definitive quantum computer, the Qmión (of approximately 32³² qubits). But... when he turns it on, something goes wrong and he is transported into the interior of the supercomputer. In this new world, governed by quantum laws, he must adapt, explore and survive if he wants to find the way back to the "classic world".
