Abstract

In our macroscopic world, we know that determining your height will not make you taller nor smaller and merely staring at an object will not change it either. The moon is up there and would stay the same whether you look at it or not. But these are acts of measurement and according to quantum measurement theory, the state of a system changes when it is measured. Here we will construct a measurement according to the postulates of quantum mechanics that does not change the state of a system.
