Entangled quantum cellular automata, physical complexity, and Goldilocks rules

چکیده
Cellular automata are interacting classical bits that display diverse emergent behaviors, from fractals to random-number generators Turing-complete computation. We discover quantum cellular (QCA) can exhibit complexity in the sense of science describes biology, sociology, and economics. QCA when evolving under 'Goldilocks rules' we define by balancing activity stasis. Our Goldilocks rules generate robust dynamical features (entangled breathers), network structure dynamics consistent with complexity, persistent entropy fluctuations. Present-day experimental platforms—Rydberg arrays, trapped ions, superconducting qubits—can implement our protocols, making testable link between computation exposed QCA.
