Well, I know if both the position and momentum are in a simultaneous eigenstate then, theoretically, we would be able to measure momentum and position without changing the wavefunction. But, is there such an eigenstate out there?(adsbygoogle = window.adsbygoogle || []).push({});

Any help is appreciated!

(sorry if the wording is awkward)
