    It is not the case that Quantum algorithms (e.g., Shor's algorithm) solve problems in polynomial time that classical models require exponential time for.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.No large-scale quantum computer yet exists; speedup claims rest on untested scalability assumptions that may fail due to decoherence or engineering limits.
      ?

      Think about whether this reason is strong or weak

    • 2.Classical algorithms like GNFS may achieve subexponential (not full exponential) factorization, reducing the gap between quantum and classical time complexity.
      ?

      Think about whether this reason is strong or weak

    • 3.Quantum measurement collapses superposition, requiring repeated trials; total wall-clock time including setup and error correction may exceed classical methods practically.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Shor's algorithm empirically demonstrates superpolynomial speedup by exploiting quantum superposition to test multiple factorizations simultaneously.
      ?

      Think about whether this reason is strong or weak

    • 2.Quantum complexity theory proves BQP problems exist outside classical P, establishing theoretical separation between quantum and classical capabilities.
      ?

      Think about whether this reason is strong or weak

    • 3.Quantum advantage has been experimentally validated on small instances, confirming the speedup mechanism works in physical systems, not just theory.
      ?

      Think about whether this reason is strong or weak
