Measuring two dynamic quantitites

  1. Apr 20, 2007 #1

    If there are two operators A and B, which commute, what are the consequences of that to the measurement of the corresponding dynamic quantities?

    That's a kind of "look up in your textbook" question isn't it? If two operators commute then their corresponding "quantities" can be simultaneously measured to any accuracy.
