Has the 2-stage Stern-Gerlach experiment been performed?

In summary, Feynman mentions that the 2-stage Stern-Gerlach experiment, which proves electron spin states to be in a superposition, has not been actually done. However, a similar experiment has been conducted on Mn@Sn12 with successful results. It is important to note that the Feynman lectures may be outdated on experimental advancements, but the theory remains reliable.

In http://www.feynmanlectures.caltech.edu/III_05.html#Ch5-S1, Feynman mentions that the 2-stage Stern-Gerlach experiment, which proves the electron spin states to be in a superposition, has never been actually done! I have also not seen any paper reporting such an experiment. My question is, has this experiment actually been done, and if so, have its results confirmed orthodox QM?

Also note that the Feynman lectures are quite old and therefore are going to be outdated on many things, especially what has been done experimentally and what has not, but that the theory remains solid.
 

Related to Has the 2-stage Stern-Gerlach experiment been performed?

1. What is the 2-stage Stern-Gerlach experiment?

The 2-stage Stern-Gerlach experiment is a physics experiment that involves passing a beam of particles through two sequential Stern-Gerlach apparatuses, each with different orientations. This experiment is used to study the quantum mechanical properties of particles, specifically their spin.

2. Why is the 2-stage Stern-Gerlach experiment important?

The 2-stage Stern-Gerlach experiment is important because it provides evidence for the quantization of angular momentum, a fundamental concept in quantum mechanics. It also helps to validate the principles of quantum superposition and entanglement.

3. How does the 2-stage Stern-Gerlach experiment work?

In the first stage of the experiment, a beam of particles is passed through a Stern-Gerlach apparatus with a specific orientation. The particles are then split into two beams based on their spin orientation. The second stage involves passing these two beams through a second Stern-Gerlach apparatus with a different orientation. This results in four distinct beams, which can be observed and measured.

4. Has the 2-stage Stern-Gerlach experiment been performed?

Yes, the 2-stage Stern-Gerlach experiment has been performed numerous times by scientists and researchers. It has been used to study the properties of various particles, such as electrons, protons, and neutrons, and has been instrumental in advancing our understanding of quantum mechanics.

5. What are the implications of the 2-stage Stern-Gerlach experiment?

The 2-stage Stern-Gerlach experiment has significant implications for our understanding of the behavior of particles at the quantum level. It provides evidence for the existence of quantized angular momentum and supports the principles of quantum superposition and entanglement. This experiment also has practical applications in fields such as quantum computing and cryptography.
