Quantum Information
From distinguishable messages to quantum communication
What can we learn, preserve, transform, and communicate when information is carried by quantum systems? Develop states, measurements, entanglement, entropy, and communication through concrete tasks, returning to nonorthogonal states, a Bell pair, and a noisy channel.
Begin reading Continue where you left off →Prerequisites and approach
No prior quantum mechanics, information theory, or linear algebra course is assumed. Probability and mathematics are introduced in context. Quantum Computing is a complementary course, not a prerequisite.
16 of 16 chapters contain draft lessons with worked examples and solved problems. These are teaching manuscripts in development; advanced results are stated with their assumptions and sources where a full proof lies beyond the course.
Read in order on your first pass. Trace each figure and model guide, reproduce the worked calculations, and try the Problems before opening their solutions. Interactive figures compare phase, noise, and measurement choices; every figure also has a static explanation.
The recurring examples are two nonorthogonal states, a Bell pair, and a noisy qubit. Their purpose changes as the course develops: first predict an observation, then distinguish, preserve, transmit, or protect a state.
