Build the quantum picture.
Understand states, amplitudes, measurements, and the physical behavior behind them. Build from the quantum rules through dynamics and correlations, then connect the ideas to the Standard Model and TRQC.
Read → try an example → check your understanding. Each lesson starts with a physical picture, adds optional technical detail, and explains every checkpoint answer. Tap any blue, dotted term for a plain-English definition.
The ideas connect
From quantum states to physical records
Follow three connected stages. Each adds tools used by the next, with six checkpoints and an interactive example in every lesson.
101
States and probabilities
States, superposition, interference, the Born rule, and measurement bases.
201
Quantum behavior and dynamics
Spin, uncertainty, evolving wave packets, energy levels, and tunneling.
301
Correlations, records, and connections
Composite states, Bell tests, decoherence, interpretations, and the path into TRQC.
Your learning path
Relativity builds the spacetime picture. The Standard Model introduces fields and interactions. This course develops their quantum language and the physics of measurement. The TRQC course then introduces its conceptual relational architecture.
How to use the course
Start with the physical picture. Try the controls and the worked example, then explain the takeaway in your own words. Open the precise version when you want the equations. You can revisit any lesson or practice an entire level at any time.
Established quantum physics. Lessons distinguish shared calculations, interpretations, and proposed changes to dynamics. The final lesson links that vocabulary to the separately labeled TRQC conceptual course.

These lessons and diagrams teach relationships. The sampling demonstration illustrates probability counting, rather than performing a physical quantum experiment. These sources give independent explanations and formal detail.
