    "abstract": "We study a two-spin quantum Turing architecture, in which discrete local\nrotations \\alpha_m of the Turing head spin alternate with quantum controlled\nNOT-operations. Substitution sequences are known to underlie aperiodic\nstructures. We show that parameter inputs \\alpha_m described by such sequences\ncan lead here to a quantum dynamics, intermediate between the regular and the\nchaotic variant. Exponential parameter sensitivity characterizing chaotic\nquantum Turing machines turns out to be an adequate criterion for induced\nquantum chaos in a quantum network.",
