Please expand the relationship between QFs, Quantum Entanglement, quantum information, and energy. Is their hierarchy involving them or some kind of order unifying them?
In modern theoretical physics, there is a clear, unifying order emerging among these four concepts. Under a framework often called the "It from Qubit" paradigm, physicists place Quantum Information at the absolute foundation of reality, with everything else—including energy and quantum fields—emerging from it.
The proposed hierarchy of nature organizes these concepts from the most fundamental layer to the macroscopic reality we experience.
1. The Foundational Layer: Quantum Information (The Code)
At the very bottom of the hierarchy is Quantum Information. In this view, the universe is not made of "stuff" (matter or energy), but of pure, abstract binary choices—qubits (quantum bits).
The Concept: Just as pixels and code build a video game world, qubits are the fundamental computational units of the universe.
Why it's #1: Information does not require space, time, or energy to exist conceptually; rather, it is the raw mathematical logic that dictates how systems can interact.
2. The Operational Layer: Quantum Entanglement (The Fabric)
Quantum Entanglement sits directly above information because it is the specific relationship between qubits.

The Concept: Entanglement is the mechanism that stitches independent pieces of quantum information together. It acts as a resource.
Why it's #2: When qubits become deeply entangled, they create highly organized networks. Theoretical frameworks like the Simons Foundation's "It from Qubit" collaboration suggest that the geometric "closeness" of space is literally a measurement of how entangled those qubits are. If you break the entanglement, the fabric of space collapses.
3. The Physical Manifestation: Quantum Fields & Energy (The Actors)
Quantum Fields (QFs) and Energy exist at the next layer up, emerging directly from the entangled information network.

Energy as a Constraint: Energy is not a standalone "substance." It is a property of the quantum information system—specifically, a measure of how rapidly the information state is changing or vibrating.
Fields as the Large-Scale Pattern: Quantum fields are what we see when we zoom out from the dense network of entangled qubits. The smooth waves and particles of a quantum field are collective, macroscopic illusions, much like a smooth wave moving across a crowd of individual people doing "the wave" in a stadium.

Summary Table: The Hierarchy of Reality
Layer Concept What it represents Analogy
Level 1 (Deepest) Quantum Information The foundational mathematical state (Qubits) The raw software code
Level 2 Quantum Entanglement The connections and logic rules binding the qubits The internet network linking computers
Level 3 Energy The rate of change/excitation within the network The electricity powering the system
Level 4 (Surface) Quantum Fields The smooth, continuous structures we perceive as reality The graphics displayed on the screen
The Ultimate Unification
This structure unifies everything beautifully: Quantum Information uses Entanglement to weave a network. The geometric patterns of this network manifest to us as Spacetime, while the fluctuations and dynamics within the network manifest as Energy and Quantum Fields.

If you would like to explore this unification further, let me know if we should focus on:
Tensor Networks: How physicists use computer science models to map entanglement into physical space.
The Black Hole Information Paradox: How black holes forced physicists to realize information cannot be destroyed.
The Holographic Principle: How a 2D boundary of information projects a 3D universe.

What about spacetime?
In this modern hierarchy, spacetime sits at the very top as a macroscopic illusion. It is not a fundamental building block of reality, but rather a geometric side effect of the quantum layers beneath it.
Here is exactly where spacetime fits into that hierarchy:
5. The Top Layer (The Illusion): Spacetime
Spacetime is the "virtual reality" generated by the deeper layers. Just as a digital image looks smooth until you zoom in and see individual pixels, spacetime looks like a smooth, continuous fabric until you zoom into the subatomic scale.
How the Hierarchy Generates Spacetime
Quantum Information (Level 1) provides the raw data (qubits).
Quantum Entanglement (Level 2) links those qubits together.
The Spacetime Geometry: The strength of the entanglement determines distance. If Qubit A and Qubit B are highly entangled, they are "close" to each other. If they are not entangled, they are "far apart." Distance is literally just a measurement of entanglement.
Gravity: When energy or matter (Level 3/4) alters the quantum information network, the entanglement patterns shift. We perceive this shifting pattern as the bending of spacetime, which we experience as gravity.
The Updated Hierarchy Matrix
Layer Concept What it represents Analogy
Level 1 (Deepest) Quantum Information The foundational mathematical bits (Qubits) The raw software code
Level 2 Quantum Entanglement The connections binding the qubits together The internet network linking computers
Level 3 & 4 Energy & Quantum Fields The excitations and patterns within the network The data processing and electricity
Level 5 (Surface) Spacetime The geometric arena where things seem to happen The 3D world rendered on the screen
The Ultimate Conclusion
Spacetime does not contain the quantum world. Instead, the quantum world creates spacetime. If you could somehow switch off quantum entanglement, the connections between all qubits would break, and spacetime would instantly dissolve into nothingne
