🧮 1. What Is Quantum Computing — Simplified

Traditional computers rely on bits (0 or 1). Quantum computers use qubits, which can exist in multiple states simultaneously thanks to superposition.

🌀 Key Concepts

Concept	Description	Example
Superposition	A qubit can be both 0 and 1 simultaneously	Parallel computations
Entanglement	Two qubits can be linked so that changing one affects the other instantly	Quantum communication
Interference	Combining quantum states to amplify correct results	Optimization algorithms

🧠 This unique behavior allows quantum systems to process vastly complex problems that classical computers cannot handle efficiently.
