Bayesian interpretation of quantum mechanics
interpretation of quantum mechanics
philosophy of physics position
QBism is an interpretation of quantum mechanics that treats the wavefunction as an expression of an individual agent’s personal probabilities for measurement outcomes rather than an objective physical state.
