Navigating the Quantum Tapestry

A quantum computer operates by processing multiple computations simultaneously across different threads of the universe's history. Observers, however, experience a singular thread and must integrate these multiple histories into a cohesive understanding through equivalences. This process of observation balances the complexity of quantum branching, suggesting that the effort required to observe might be on par with the number of branching histories. The comparison of observational effort and computational effort highlights the intricate relationship between observation and computation, indicating that while both can theoretically be handled by a Turing machine, practical implementation of equivalence may be more effective through string rewriting models.
