Q: What is the “monogamy of entanglement”?

Physicist: The Monogamy of Entanglement is the statement that “maximally entangled” particles only show up in pairs. Entangled particles follow the same rule that single particles follow: wrong measurement = random result, correct measurement = definite result. How entanglement is defined: When you don’t have access to both entangled particles and are forced to measure them one at a time, you get random results. A maximally entangled pair of particles has “1 ebit” of entanglement and a separable pair of particles has 0 ebits. Like many seemingly arbitrary mathematical definitions, it turns out that the monogamy of entanglement is a powerful, useful statement.
