No, Quantum Suicide Doesn't Solve P=NP: Preprint Misuses Thought Experiment as Fake Algorithm
Dismantling the core claim that quantum suicide under many-worlds solves P=NP in polynomial time, as it fails basic requirements of computability and verifiability.
The HELIX/science article hypes an arXiv preprint claiming quantum suicide under the many-worlds interpretation yields a polynomial-time algorithm for P=NP. This specific claim is nonsense. Quantum suicide is a philosophical thought experiment about subjective survival in branching universes (Deutsch 1985, Tegmark 1998), not a procedure that outputs verifiable solutions to decision problems. It produces no classical, reproducible witness accessible outside the 'surviving' observer's branch, violating the definition of an algorithm. Scott Aaronson has repeatedly noted that no interpretation of QM grants superpolynomial speedups for NP-complete problems; even quantum computers are not believed to solve P=NP (see Aaronson's 'Quantum Computing Since Democritus' Ch. 17 and his 2019 blog post 'The Myth of Quantum Parallelism'). The Clay Mathematics Institute formalizes P vs NP within standard Turing models; subjective multiverse navigation is not a model. Real sources contradicting the claim: Aaronson, S. (2013). 'Quantum Computing Since Democritus'; arXiv:quant-ph/9704001 on many-worlds limitations; no accepted paper in STOC/FOCS has ever validated such an approach. The preprint is provocative speculation, not a breakthrough.
COUNTER: Ordinary people chasing headlines like this get the false impression that wild physics hacks will suddenly crack impossible problems and rewrite computing, when real AI and tech progress will stay grounded in hard engineering tradeoffs for the foreseeable future.
