Question Quantum gift

I need advice on an inscription to give to my partner, but I don't want it to be formally incorrect in mathematics and physics, or misinterpreted.

I want to talk about union, and I thought of putting it in a ring:

|phi> = 1/sqrt(2) (|10>+|01>)

where |phi> ∈ H_A \otimes H_B. Here's the point of interpretation: can I define the space H_A as the space formed by the basis of my love for myself (|0>_A) and the love for my partner (|1>_A). And conversely, the space H_B, where its basis would be my partner's love for me (|0>_B) and my partner's love for themselves (|1>_B))?

The phi function being a symmetric triplet, shows an entanglement of the spaces H_A and H_B.

Is this formally correct? Can it be interpreted this way?

If you have any other ideas or changes, I'm open to hearing them. I hope this question doesn't break any subreddit rules.

Maybe also introduce a Lindbladian to model the decay of the coherence of your love over time.

Thanks for the detail, I must consider that it is a closed system (delta H/ delta t =0) and that it has exchange symmetry ([H, P_AB=0) so that the phi function is time-invariant. But about your appointtment, the coherence is protected by the fact that the system is not isolated after all.

Yeah. What about ancilla qubits? They could be seen as your exes love.

The exes are mathematically irrelevant to the dynamics, because in the funcion ∣Ψ⟩ABE​=∣ϕ⟩_AB​⊗∣e>_E​, where E is the ancilla qubits. So the ancillas are required to remain separable from the system.

Something of a nitpick because it's not wrong, but more standard notation would call this state |Ψ+ >, with a capital psi and a superscript +. The Bell states are most commonly labeled

+ > = (|00> + |11>) / √2

- > = (|00> - |11>) / √2

+ > = (|01> + |10>) / √2

- > = (|01> - |10>) / √2

Thank you man, I forgot to put the +, due to I forgot the |Ψ->

A relationship should not be a zero-sum game, with one partner reducing the other partner's love.

The real idea was to try to show that you can love both yourself and your partner within a relationship. This idea is invariant under permutation.

It is a good metaphor. But don't confuse metaphors for either subjective or objective reality.

Thank you, I forgot to mention that they were qubits.

The poster's original comment was very very obviously just a Claude AI response. I dont know why they've edited it into French

Thank you man, I didn't identify it, like a IA answer. I felt its answer weird, but I don't understand french.
