The story centers on a woman who is a trained physicist who is waiting to see her twin sister, Chloe, for the first time in years. She is waiting to show her how she has found the “hidden local variables” of the quantum entanglement of Electrons and Positrons. When she shows this to Chloe, she takes the local variables (seemingly superpowers of acquiring knowledge) and Chloe gives herself up to her and they become one person.
The example of quantum entanglements is based on experiments with light, which is made of photons. Light can be shined on something called a polarizer. Each photon reaching the polarizer will either pass through or be absorbed. The story accurately portrays Pions decaying into Electrons and Positrons. It also accurately portrays ‘spin’, which is basically where a particle goes in the magnetic field it belongs to. The story obviously exaggerates science with the local variables as supernatural abilities of acquiring knowledge and two humans morphing together; these things have no scientific basis.
