## Main Question or Discussion Point

As a Computer Programmer, it's hard to wrap my head around Quantum Entanglement and non locality being explained in the context of Classical Physics. In other words, if the universe at it's core is physical where does Quantum Entanglement fit within a physical picture of reality?

There's been talks by Physicist like John Preskill that says space-time is a quantum error correcting code. This would mean most of space is physical qubits doing quantum correction to protect any code running on logical qubits.

Here's a paper published by Physicist Paola Zizzi who talks about Computational Loop Quantum Gravity.

It makes sense to me to me to design a program where I have random red dots moving around on the computer screen and the program is coded in a way that when a red dot gets entangled with another red dot and I click on that red dot, the red dot it's entangled with turns green. I can then extrapolate my computer screen to the size of the universe and I can click on a red dot on one side of the universe and instantly, the red dot it's entangled with will turn green even if it's on the other side of the universe. So subatomic particles would be like pixels on a space-time screen.

So my question is, how does Quantum Entanglement and non locality fit within a physical model?

**Holographic quantum error-correcting codes: Toy models for the bulk/boundary correspondence**https://arxiv.org/abs/1503.06237We propose a family of exactly solvable toy models for the AdS/CFT correspondence based on a novel construction of quantum error-correcting codes with a tensor network structure. Our building block is a special type of tensor with maximal entanglement along any bipartition, which gives rise to an isometry from the bulk Hilbert space to the boundary Hilbert space. The entire tensor network is an encoder for a quantum error-correcting code, where the bulk and boundary degrees of freedom may be identified as logical and physical degrees of freedom respectively. These models capture key features of entanglement in the AdS/CFT correspondence; in particular, the Ryu-Takayanagi formula and the negativity of tripartite information are obeyed exactly in many cases. That bulk logical operators can be represented on multiple boundary regions mimics the Rindler-wedge reconstruction of boundary operators from bulk operators, realizing explicitly the quantum error-correcting features of AdS/CFT recently proposed by Almheiri

**Computability at the Planck scale**https://arxiv.org/abs/gr-qc/0412076We consider the issue of computability at the most fundamental level of physical reality: the Planck scale. To this aim, we consider the theoretical model of a quantum computer on a non commutative space background, which is a computational model for quantum gravity. In this domain, all computable functions are the laws of physics in their most primordial form, and non computable mathematics finds no room in the physical world. Moreover, we show that a theorem that classically was considered true but non computable, at the Planck scale becomes computable but non decidable. This fact is due to the change of logic for observers in a quantum-computing universe: from standard quantum logic and classical logic, to paraconsistent logic.

It makes sense to me to me to design a program where I have random red dots moving around on the computer screen and the program is coded in a way that when a red dot gets entangled with another red dot and I click on that red dot, the red dot it's entangled with turns green. I can then extrapolate my computer screen to the size of the universe and I can click on a red dot on one side of the universe and instantly, the red dot it's entangled with will turn green even if it's on the other side of the universe.
