An Introduction to QBism with an Application to the Locality of

Since probabilities are the personal judgments of an agent, it follows that a quantum state assignment is also a personal judgment of the agent assigning that state.13 The notorious “collapse of the wave-function” is nothing but the updat ...

The Learnability of Quantum States

The Consistent Histories Interpretation of Quantum Mechanics
