This is the essence of Heisenberg’s uncertainty relation, which is to be explained in more detail in the sections below.ħ.2 Preparation of position and momentum for photons position and momentum) whose simultaneous preparation is fundamentally impossible, although the preparation of the individual properties does not come up against any fundamental limits. polarization properties with photons), it is not possible to prepare several at the same time. Pairs of properties exist (e. two properties, does not pose any problems in principle in classical physics.Īlthough individual properties for an ensemble of quantum objects can be prepared in quantum physics (e. This simultaneous preparation for position and momentum, i. “Prepare” means that the spread of the measured values is zero or very small when measurements of the prepared quantity are undertaken on an ensemble of balls. identical values of the launch position and the launch velocity. Using the example of the horizontal throw, as familiar from the example of the catapult from Chapter 2, we recognize that position and momentum have to be prepared simultaneously to produce identical initial conditions, i. In preparation for understanding the Heisenberg uncertainty relation, we will again discuss the preparation of properties concept (preparation). 7.1 Simultaneous preparation of different properties

You can download the slightly more detailed Chapter 7 of the teaching materials as a pdf file to help you. This chapter shows how it can be expressed as a statement about the ability to simultaneously prepare properties. The Heisenberg uncertainty relation is often seen as one of the most important insights of quantum mechanics. Implementations of joint measurements of position and momentum and commentīriefly on the status of experimental tests of the uncertainty principle.7.1 Simultaneous preparation of different properties – 7.2 Preparation of position and momentum for photons – 7.3 A measure for the “quality” of a preparationħ.4 Measurement method and properties – 7.5 Electrons at the single slit and quantitative expression of the uncertainty relationħ.6 Uncertainty relation and path concept – 7.7 Progress check – 7.8 Summary Finally, we survey models and experimental
