Discussion Overview

The discussion revolves around the concept of quantum tunneling across possible worlds, particularly in the context of the Many-Worlds Interpretation (MWI) of quantum mechanics. Participants explore the implications of this idea, including the existence of a hyper-dimensional plane that could facilitate such tunneling and the nature of qubits in relation to this concept.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether it is possible to quantum tunnel across possible worlds and suggests the existence of a hyper-dimensional plane that could enable this.
  • Another participant asserts that quantum tunneling across possible worlds is not possible, emphasizing that the term "world" in quantum mechanics has a different meaning than in everyday language.
  • A follow-up question asks if all qubits in different worlds perform the same quantum task when one qubit is engaged in a task.
  • Another participant responds that the question regarding qubits is unrelated to the original inquiry and indicates that it does not have a sensible answer.
  • A later reply suggests that the original question has been answered and implies that further understanding of quantum mechanics and MWI will come from formal education or specific literature.

Areas of Agreement / Disagreement

Participants express disagreement on the feasibility of quantum tunneling across possible worlds, with some asserting it is not possible while others explore the hypothetical implications. The discussion remains unresolved regarding the nature of qubits in this context.

Contextual Notes

There are limitations in the discussion regarding the definitions of "world" and the assumptions made about quantum mechanics and its interpretations. The relationship between qubits and their operations across possible worlds is also not clearly defined.

Who May Find This Useful

This discussion may be of interest to those studying quantum mechanics, particularly in relation to the Many-Worlds Interpretation, as well as individuals curious about the conceptual implications of quantum tunneling and its hypothetical applications.

TL;DR
Hyper-dimensionality in MWI
Forgive my poor lingo. As my bio states, I only have a complete degree in HS.

Is it possible to quantum tunnel across possible worlds?

If so, is there a hyper-dimensional plane where this would be made possible?

And if so, how would you conceptualize or describe it?

Information breakage should not be an issue if in a 4D-plane they such system would both occupy?

I should be more specific and state that this all hypothetically may occur in the MWI...

No.
When people use the word “world” in talking about quantum mechanics and the MWI, they mean something altogether different from what the word means in ordinary English usage.

Can you tell me that is a qubit is working on a quantum task, all qubits in other worlds respectively are also doing the same task?

That's not how quantum computers work so that question (which appears unrelated to your original question) has no sensible answer.
 
The question in the original post of this thread has been answered so this thread is closed.

@TunnelingthuWorlds, your bio says that you are currently an undergrad, so you may be taking a course in quantum mechanics in the next year or so. When you do, you'll have a much better sense of what QM and the MWI really are. Sadly, most of what you'll read outside of textbooks and the professional literature is oversimplified to the point of being misleading.

If you don't want to wait, Giancarlo Ghirardi's book "Sneaking a look at God's cards" is a good high-school level way of approaching QM. It oversimplifies, but much less then any of th popularizations you'll find out there.
