Quantum evidence of nonlocal consciousness during clinical death.

If consciousness can operate under quantum principles, then the boundaries between life, death, and cognition are far more permeable than current science allows. In the first large-scale, randomized, double-blind, multicenter trial to test this possibility, conducted across 13 hospitals in the UK and Spain, we investigated whether the human mind can access information during clinical death-but only when exposed to auditory stimuli governed by quantum entanglement. The entangled stimulation circuit was implemented and synchronized with the 127-qubit IBM Brisbane quantum supercomputer and delivered during in-hospital cardiopulmonary arrest (CA), beginning 120 s after arrest onset. Quantum entanglement was verified through statistically significant violations of Mermin inequalities. During resuscitation, we measured neurophysiological biomarkers including cerebral oxygenation via near-infrared spectroscopy (NIRS), brain temperature, and blood pH, lactate, and serum concentrations of brain-derived neurotrophic factor (BDNF). After reanimation, 142 survivors completed a forced-choice recall test, near-death experience (NDE) scales, and other clinical control assessments. False memories, hallucinations, and confounding biases were successfully controlled. Notably, recall lucidity increased momentarily as NIRS values dropped, and NDEs positively correlated with neuroplasticity during CA. Biomarker models explained up to 56.8% of the variance in recall. These findings compel a radical rethinking of clinical death: consciousness may persist-quantum bound, detectable, and not yet defeated.
