Question about superposition and measurement
Reply to thread
Message
[QUOTE="DrChinese, post: 5508612, member: 323"] Quantum particles have a number of observable properties. Certain pairs (such as position and momentum) of those are non-commuting; in that case, a definite value for one means a superposition for the other. It is possible to measure and thus change which is in a superposition. This can even be done without affecting other pairs of observables (if done properly). Further, it is possible to perform partial measurements on an observable so its state is not exactly known (and it is therefore in a partial superposition). Once you grasp the above, you will understand the significance of Nugatory's excellent comments. [B]Learn more before attempting to form a picture.
