... The reason for the repetition is that quantum mechanics does not make definite predictions for the position, momentum, etc. When we do the exact same measurement on identically prepared systems, we do not get always get the same result, as we do in classical mechanics. But probability distributions ...

... Any pure state of a spin-1/2 (or a photon) can be represented as a point on the surface of the sphere – it is parametrized by a single amplitude and a single relative phase. This is the same as the description of a classical spin, or the polarisation (Stokes parameters) of a classical light field. O ...

Manipulating and Measuring the Quantum State of Photons and Atoms
... (2) Both density matrices and superoperators we measure typically are very sparse... a lot of time is wasted measuring coherences between populations which are zero. (a) If aiming for constant errors, can save time by making a rough msmt of a given rate first and then deciding how long to acquire da ...

Conclusive Exclusion of Quantum States
... Introduction. Suppose we are given a single-shot device, guaranteed to prepare a system in a quantum state chosen at random from a finite set of k known states. In the quantum state discrimination problem, we would attempt to identify the state that has been prepared. It is a well known result [1] t ...

The function must be continuous The function must be differentiable the particle exists and so the the probability of finding it throughout all of space must be equal to 1. When this is the case, the funct ...
