“Quantum Mechanics: The Physics of the Microscopic World” S:1 E:9 States, Amplitudes, and Probabilities

S:1 E:9 States, Amplitudes, and Probabilities The interferometer from the previous lecture serves as a test case for introducing the formal math of quantum theory. By learning a few symbols and rules, you can describe the states of quantum particles, show how these states change over time, and predict the results of measurements.
