The Quantum Advantage
Quantum algorithms exploit superposition, entanglement, and interference to solve specific problems exponentially or quadratically faster than classical computers. They're not universally better—but for the right problems, they're revolutionary.
⚡Types of Speedup
Exponential
Problems that take centuries → minutes
Example: Shor's algorithm
Quadratic
√N speedup for search problems
Example: Grover's algorithm
Heuristic
Better solutions, speedup unproven
Example: QAOA
🎯When Quantum Wins
