The Silence Experiment: A Multi-State Protocol for Detecting Consciousness-Dependent Decoherence in Shielded Environments

A controlled experimental protocol for testing the von Neumann–Wigner (VNW) interpretation of quantum mechanics — the hypothesis that consciousness plays a role in quantum state reduction — against the prevailing environmental decoherence framework (Zurek, Zeh, Joos). The experimental platform places a single experienced meditator in states showing EEG patterns consistent with objectless awareness inside a shielded environment. A quantum coherence sensor measures decoherence rates across seven controlled conditions spanning the full cognitive-excitation axis. The primary pre-registered test is the ordered prediction T_coherence(cessation) > T_coherence(baseline) > T_coherence(active cognition). The simple cessation-vs-empty-chamber comparison is a secondary test. All other cross-condition comparisons are treated as exploratory. A secondary experiment uses quantum random number generators with improved shielding, blinding, and instrumentation. The protocol is phased: a Phase 0 proof-of-concept using nitrogen-vacancy centers in diamond, and a Phase 1 full protocol using superconducting qubits in an underground laboratory. The protocol employs triple-blind analysis and pre-registered statistical thresholds. Phase 0 can detect medium-to-large effects (d > 0.3). It is not designed or powered to test small-effect claims from the prior literature. Null results establish pre-registered upper bounds; positive results require replication. The theoretical basis for this protocol is detailed in the companion paper, The Silence Paradigm.
