Conditions for interaction in the quantum world

In summary, the conditions necessary for the collapse of a wave function of an electron, photon, or an atom (particularly an alpha particle) depend on one's interpretation of quantum mechanics. Decoherence is a relevant concept. The wavelength may also play a role, as seen in a video where the wave function does not collapse in a box. A higher mass can make it easier for the wave function to collapse. The outcome of a later interaction with a collapsed wave function depends on the specific setup.

What are the conditions necesairy to collapse a wave function of a electron, photon or an atom (alpha particle mostly?).

Wavelength? Asking because I cannot understand why in this video the wave function does not collapse in this box.


Seems like in the outside there should be massive interference?

If the mass is higher, is it easier for the wave function to collapse?

And related, let;s say light behaves as a wave, I let it collapse with some interaction, what happens if there is another interaction later on (before it would hit a final destination), does it spread out again?

That depends on your favorite interpretation of quantum mechanics. Decoherence is certainly a relevant concept here.

Where in the video?

In general, yes.

Depends on the setup.

FAQ: Conditions for interaction in the quantum world

1. What is the quantum world?

The quantum world is the realm of physics that deals with the behavior and interactions of subatomic particles, such as electrons, protons, and photons. It follows a set of rules and principles that are different from those of classical physics and governs the behavior of matter and energy at a very small scale.

2. What are the conditions for interaction in the quantum world?

The conditions for interaction in the quantum world are governed by the laws of quantum mechanics, which include principles such as superposition, entanglement, and uncertainty. These principles dictate how particles can exist in multiple states at once and how they can influence each other's behavior without direct physical contact.

3. How do particles interact in the quantum world?

In the quantum world, particles interact through the exchange of energy, such as photons or other particles. This exchange can occur through processes such as absorption, emission, or scattering. The strength and nature of these interactions are determined by the properties of the particles involved and the laws of quantum mechanics.

4. Can particles in the quantum world interact with each other at a distance?

Yes, particles in the quantum world can interact with each other at a distance through the principle of entanglement. This allows particles to become connected in such a way that the state of one particle can affect the state of the other, even if they are separated by large distances. This phenomenon has been demonstrated through experiments and is an essential aspect of quantum communication and computing.

5. What are the implications of conditions for interaction in the quantum world?

The conditions for interaction in the quantum world have significant implications for our understanding of the universe and our technological capabilities. They have enabled the development of technologies such as transistors, lasers, and MRI machines. They also hold the promise of revolutionizing fields such as computing, communication, and cryptography, as well as providing insights into the fundamental nature of reality.
