    "abstract": "Entanglement distance is the maximal separation between two entangled\nelectrons in a degenerate electron gas. Beyond that distance, all entanglement\ndisappears. We relate entanglement distance to degeneracy pressure both for\nextreme relativistic and non-relativistic systems, and estimate the\nentanglement distance in a white dwarf. Treating entanglement as a\nthermodynamical quantity, we relate the entropy of formation and concurrence to\nrelative electron distance, pressure, and temperature, to form a new equation\nof state for entanglement.",
