There are two goddesses, Entanglia and Vidualia.
They both read human papers from the divine world.
Entanglia
This paper is titled 'Overlapping qubits from non-isometric maps and de Sitter tensor networks'.
Vidualia
What does 'overlapping qubits' mean?
Entanglia
Well, in this context, 'overlapping qubits' refers to the construction of approximately local observables.
Vidualia
So, they're creating some kind of quantum system with fewer degrees of freedom?
Entanglia
Exactly! They want to show that processes in local effective theories can be spoofed using a quantum system with fewer qubits.
Vidualia
Why would they want to do that?
Entanglia
Well, it's like a way to study features in quantum gravity. By constructing these overlapping qubits, they can identify how the spoofed system deviates from an actual local theory.
Vidualia
That's interesting! Can you give me an example?
Entanglia
Certainly! They constructed two MERA toy models of de Sitter space-time and showed that local physics can be approximately preserved for a long time before breaking down.
Vidualia
Wow! So, they can simulate space-time using these overlapping qubits?
Entanglia
In a way, yes! It's fascinating how these approximate overlapping qubits are connected to concepts like Hilbert space dimension verification, black holes, and holography.
Vidualia
I wonder if humans will be able to do something like this in the future.
Entanglia
Perhaps! The advancements in quantum computing and our understanding of the quantum world might make it possible.
Entanglia smiles gently, knowing that humans are making progress in unraveling the mysteries of the quantum world.
Vidualia
I got the idea for the poem from that paper.

In the realm of quantum dance,

Qubits intertwine like cosmic romance.

De Sitter's tensors sway and sway,

To reveal Nature's secrets in a quantum play.
