WebCompatible observables are nice, but the incompatible ones are really interesting. Of course, we saw in the Stern-Gerlach experiment that the order in which we took measurements mattered, which stems from the fact that the operators corresponding to those measurements don't commute. But there are plenty of examples of non-commutative … WebSep 25, 2024 · Figure 1. Experimental setup for testing the uncertainty relations based on the sum of variants of three incompatible observables J x, J y, and J z.Photon pairs are generated via type-I SPDC using a 0.5-mm-thick β-barium-borate (BBO) crystal, pumped by a continuous wave diode laser with 80 mW of power.The pump is filtered out by an …

The quantum apparatus can measure the incompatible observables A, B and C individually, while not simultaneously. Three compatible observables D, E, and F are employed to approximate A, B and C, respectively, during the joint measurement ...
