Chapter 1 Introduction
... At the risk of becoming slightly redundant at this point, we emphasize again that the outcomes of measurements in quantum mechanics are random. Of course, this feature may be taken as a shortcoming of the theory: One might argue that the theory does not “provide the full story”. Surely the state of ...

The Learnability of Quantum States
... Could that be easy, even if sampling from DC itself was hard? To rule that out, we need to show that even a fast classical algorithm for QSAMPLING would imply P#P=BPPNP ...

Wave mechanics and the Schrödinger equation
... We turn now to the second ground-breaking experiment in the development of quantum theory. When a metallic surface is exposed to electromagnetic radiation, above a certain threshold frequency, the light is absorbed and electrons are emitted (see figure, right).

... the potential energy E of the pendulum is E = mgx = 1,492 · 10−6 J. Applying the quantum equation E = nhν, since in this case hν = 3,301 · 10−34 J, we find the numer of quanta to be n = 4,5 · 1027 !!! What is the moral of the story? To measure the discrete character of energy in a macroscopic system ...
