Abstract

Eleven experiments (H-500 to H-510) investigating Integrated Information Theory (IIT) in quantum systems on IBM Quantum hardware (ibmₘarrakesh, 156 qubits) and GPU. Includes IIT 4. 0 upgrade with cause-effect repertoires, falsifiability testing (8/8 Popper predictions passed), topological Phi (Betti numbers, Euler characteristic), QEC preserves Phi (+0. 0203 bits), entangled vs separable Phi (1147x ratio), BB84 QKD on real hardware (QBER=0% without Eve, 14-15% with Eve), and quantum-secure authentication channel combining BB84 with Transformer V9 tokens. 14 IBM Quantum jobs, 202 PUBs recovered.
