B Are Molecules Entangled Across Distances in Biochemistry?

Rainbows_
Nucleus are entangled to electrons...
Atoms are entangled to other atoms in molecules..

Are molecules at distance also entangled to one another? Is there a way to test if this is true?

I want to know if our biochemistry is entangled to the biochemistry of other people.

Essentially any interaction between two systems will entangle them. But entanglement is "delicate" in that it can also easily break if either of your systems interact with anything else. This is especially true if you're talking about a biological system at body temperature, where effects of quantum coherence are negligible. So you expect some entanglement between particles "close enough" to each other to interact often, but essentially no entanglement between individual molecules in two different people.

Thread entangled for Moderation...

EDIT -- Thread will remain entangled.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
