PPT – Core Lecture (13 slides)
Deep space/quantum orbital theme with Bloch sphere diagrams, qubit visuals, and custom-drawn circuit elements. Covers: Classical bit vs Qubit comparison (with Bloch sphere) → Superposition with full mathematical notation (|ψ⟩ = α|0⟩ + β|1⟩) → Entanglement diagram with practical applications → 4 Quantum Gates (H, X, CNOT, Z) → Cryptography threat table (RSA/ECC/AES vs Shor’s/Grover’s) + Post-Quantum solutions → Quantum AI & Science (6 sectors) → 2 Worked Examples (Shor’s Algorithm step-by-step; Grover’s vs classical database search with calculations) → Limitations (decoherence, error rates, qubit count) → Future roadmap timeline → Practice + Summary.

Worksheet (56 marks)
Four sections: Foundations (qubit definition, comparison table, superposition probability calculations, entanglement), Quantum Gates & Algorithms (gate functions, Shor’s explanation, Grover’s calculations with actual numbers), Applications (drug discovery, PQC standards, real-world uses), and Limitations & Future (technical challenges + evaluation essay).

Activity – Quantum Think Tank (~50 min)
Four parts: group investigation challenges (Qubit Power calculations / Crypto Doomsday timeline / Quantum Medicine research / Algorithm Race table), a Superposition Calculator where students compute probability amplitudes for 5 different qubit states, a Crypto Doomsday debate using a 2031 scenario where RSA has been cracked, and a quantum hardware comparison table (IBM/Google/IonQ/D-Wave). Extension: critically evaluate Google’s quantum supremacy claim.

MCQ Quiz (12 questions)
Covers 2ⁿ states calculation, probability amplitude maths, Shor’s vs Grover’s algorithms, decoherence, H-gate function, entanglement, CRYSTALS-Kyber, Grover’s step count, operating temperature, NISQ era definition, and drug discovery applications.
