We introduce a Maxwell demon which generates many-body entanglement robustly against bit-flip noises, allows us to obtain quantum advantage. Adopting the protocol of voter model used for opinion dynamics approaching consensus, randomly selects qubit pair and performs feedback control, in continuous repetitions. derive upper bounds entropy reduction work extraction rates by demon's operation, ar...

It is often assumed that implicit learning of skills based on predictive relationships proceeds independently of awareness. To test this idea, four groups of subjects played a game in which a fast-moving "demon" made a brief appearance at the bottom of the computer screen, then disappeared behind a V-shaped occluder, and finally re-appeared briefly on either the upper-left or upper-right quadra...
