New Research Shows Decision-Making Needs Both Quantum and Classical Worlds

Chapman University researchers discovered that decision-making and intelligence cannot exist in purely quantum systems because quantum mechanics prevents copying and comparing information—essential processes for evaluating choices. Their study found that agency requires classical resources like stable, copyable information that emerges through decoherence, where quantum superpositions collapse into definite outcomes. This means both consciousness and quantum artificial intelligence must rely on hybrid quantum-classical architectures rather than operating in purely quantum realms.
