From qubits and superposition to Grover's algorithm and quantum machine learning — a complete guide to computation beyond classical limits.
Unit I builds the mathematical and conceptual foundation every other unit depends on. Nine lectures across six core topics.
Why classical bits hit a wall on certain problems, and how the quantum model of computation breaks through it with superposition and parallelism.
The state |ψ⟩ = α|0⟩ + β|1⟩, what the Born rule means, and how every qubit state maps to a point on a 3D sphere surface.
How observation collapses superposition, why this is irreversible, what Schrödinger's cat really illustrates, and why algorithms must measure last.
The universal shorthand of quantum mechanics: kets, bras, inner products, orthonormal bases, and how matrix operations translate into gate operations.
Bell states, non-local correlations, the 2022 Nobel Prize, and why entanglement is a computational resource rather than just a curiosity.
Superconducting, trapped-ion, photonic and topological qubit technologies, plus hands-on circuit programming with IBM's open-source Qiskit SDK.
A complete study guide and an interactive quiz — everything you need to prepare for Unit I.
A fully interactive HTML reference covering every topic in Unit I with explanations, diagrams, comparison tables, Dirac notation tables, a Bloch sphere diagram, and a Qiskit code example.
Test your understanding with 5 carefully crafted questions. Every wrong answer shows a detailed explanation of the concept so you learn from mistakes, not just avoid them.
Introduction to Quantum Computing prepares you to design quantum algorithms, implement them in Qiskit, and understand their real-world applications in cryptography, optimization, and machine learning.
Each unit builds on the previous. Unit I fundamentals appear in every subsequent topic.
