Third lecture, 21.10.03 (von Neumann measurements, quantum
... Any time two systems interact and we discard information about one of them, this can be thought of as a measurement, whether or not either is macroscopic, & whether or not there is collapse. The von Neumann interaction shows how the two systems become entangled, and how this may look like random noi ...

The postulates of Quantum Mechanics
... This second postulate outlines another strange possibility: quantum non-locality. If both systems S1 and S2 are well separated in space, the entangled state Ψ of S1 + S2 is a manifestation of non-locality, but a non-locality in a correlated manner, because if we measure a physical quantity for the f ...

This paper presents a sophomore-level experiment that allows students to see the “particle-in-abox” behavior of a real system (quantum dots of different sizes) and explores the temperature dependence of the quantum dots’ energy gap. Quantum dots are nanometer-sized clusters of atoms that contain any ...
