Holographic Quantum Channel Advantage in NISQ Hardware: From Handshake to Quantum Switch

We present experimental evidence that the [[5,1,3]] perfect quantum error-correcting code produces measurably superior inter-system correlation protection compared to generic Clifford encoders in superconducting quantum hardware. Five main results are reported: (1) hardware validation on IBM Quantum ibm_kingston yields ZZ_holo = +0.46 vs ZZ_rand = +0.025 (p=0.0265); (2) a 9-level capacity curve on ibm_fez confirms |ZZ_holo| = 0.692 vs |ZZ_rand| = 0.084 (t=32.057, p≈0, ratio 8.3×); (3) all-qubit noise experiment confirms amplitude plateau independent of noise level (t=25.265, p≈0); (4) inter-branch conditional correlations C_holo = 0.367 vs C_rand = 0.002 (ratio 172×, p=0.004); (5) Quantum Switch with holographic encoding yields coherence ratio 20× over random encoders (p=0.047). The holographic channel achieves CHSH = 2√2 exactly, confirming standard quantum mechanics. A Leggett-Garg violation K=1.106 > 1 is confirmed from existing hardware data (p=0.0015). All null results are reported with equal prominence. All experiments were pre-registered before data collection.
