Angular Momentum in Quantum Mechanics - Jiwaji University
www.jiwaji.eduSimilarly, in quantum mechanics, angular momentum plays a central role in under-standing the structure of atoms, as well as other quantum problems that involve rotational symmetry. Like other observable quantities, angular momentum is described in QM by an operator. This is in fact a vector operator, similar to momentum operator. However, as we ...
C191 -Lectures 8 and 9- Measurement in Quantum Mechanics
inst.eecs.berkeley.eduthe physics of a measurement: a quantum system in a superposition state is combined with a meter, leaving the two in an entangled state - then the qubit is thrown out, and the state of the meter is a classical probability distribution. Quantum mechanics utterly fails at telling us how wave function collapse actually works. We could keep adding

qitd114 Hilbert Space Quantum Mechanics
quantum.phys.cmu.edu⋆ In quantum mechanics a two-dimensional complex Hilbert space H is used for describing the angular momentum or “spin” of a spin-half particle (electron, proton, neutron, silver atom), which then provides a physical representation of a qubit. The polarization of a photon (particle of light) is also described by d= 2, so represents a qubit.
