 186    without running itself, which defeats the purpose. -/

 192/-! ## Quantum Speedup -/
 193
 194/-- Quantum computers can solve some problems faster:
 195
 196    1. **Factoring**: Shor's algorithm (exponential speedup)
 197    2. **Search**: Grover's algorithm (quadratic speedup)
 198    3. **Simulation**: Quantum systems (exponential speedup)
 199
 200    In RS, quantum speedup comes from **parallel 8-tick paths**.
 201    Superposition = exploring multiple ledger branches. -/

 208/-- **THEOREM**: Quantum parallelism from 8-tick superposition.
 209
 210    The 8-tick structure allows:
 211    - Multiple phases simultaneously
 212    - Interference between paths
 213    - Measurement collapses to one outcome -/
 214theorem quantum_parallelism_from_8tick :
 215    -- Superposition = multiple 8-tick phases
 216    -- Interference determines probabilities
 217    -- Measurement selects one outcome
