The Kochen-Specker Theorem and Contextuality
The Kochen-Specker theorem shows that quantum outcomes cannot all be fixed in advance independent of context. Proofs, experiments and meaning.
Quantum State Estimation From Limited Measurements
How quantum states are estimated from limited measurements: tomography, maximum likelihood, Bayesian inference and adaptive methods.

Quantum social science borrows quantum models to describe human behavior and groups. Its ideas, applications and the objections raised.
Quantum Cognitive Models: Probability, Reconsidered
Quantum cognitive models apply quantum probability to memory, judgment and decision-making. What they explain and how they are tested.
Quantum Error Detection: Knowing Without Fixing
Quantum error detection flags errors without correcting them. Syndrome measurement, detection codes and their role in fault-tolerant systems.
Quantum State Discrimination: Telling States Apart
How to tell quantum states apart: minimum-error and unambiguous discrimination, the Helstrom bound, tomography and experimental implementations.
Quantum State Tomography: Measuring an Unknown State
Quantum state tomography reconstructs an unknown quantum state from many measurements. The methods, maximum likelihood estimation and its costs.
Quantum Principal Component Analysis (QPCA)
Quantum principal component analysis finds the main directions in data using phase estimation. How it compares with classical PCA and its caveats.
