IBM Quantum Learning

This learning path focuses on practical quantum computation, circuit building, and quantum mechanics, using IBM Quantum Learning resources and the Qiskit software development kit.

📅 Progress & Lesson Summaries

Lesson 1: Build and Run Your First Quantum Program

  • Summary: Transitioning from visual circuit design on IBM Composer to programmatic circuit creation in Qiskit.
  • Core Concepts:
    • IBM Composer: Dragging and dropping gates on a visual timeline (circuit diagram) to explore state changes.
    • The Hello World Circuit: Creating the $\vert\Phi^+\rangle$ Bell state using a Hadamard ($H$) gate on qubit 0 followed by a Controlled-NOT ($CX$) gate with qubit 0 as control and qubit 1 as target.
    • Simulators vs. QPUs: Running job executions on a perfect local simulator vs. a real physical IBM Quantum Processing Unit (QPU) affected by environmental decoherence, read-out errors, and noise.

Lesson 2: Quantum Mechanics Basics

  • Summary: Exploring the mathematical foundations of quantum systems and state transitions.
  • Core Concepts:
    • State Vector Representation: Describing qubit states using Dirac notation (ket vectors $\vert \psi \rangle$) and matrices.
    • Superposition Math: Restricting state amplitudes to the normalization condition $\vert\alpha\vert^2 + \vert\beta\vert^2 = 1$.
    • Bloch Sphere Coordinates: Parameterizing the state vector using polar ($\theta$) and azimuthal ($\phi$) angles.
    • Measurement Collapse: Explaining why a quantum state collapses to classical eigenvalues upon physical measurement.
