Popular Summary Superconductivity originates from the pairing up of electrons in what are called Cooper pairs. But theory also hints at fundamentally new types of superconducting states that could emerge from electron quartets (two Cooper pairs) or sextets (three Cooper pairs). Despite intensive theoretical studies, the basic properties of such states—and even the question of whether they exist—remain mysterious due to a lack of experimental evidence.
