Round 9: Tossup 5

Popular examples of qubits that rely on this phenomenon include transmon and flux qubits. Niobium-titanium and niobium-tin alloys are useful because they display this phenomenon. SQUIDs are made up of loops displaying this phenomenon that take advantage of the Josephson effect between two materials exhibiting it. This phenomenon is exhibited by the ceramic (*) yttrium barium (-5[1])copper (10[1])oxide. According to BCS theory, this phenomenon arises from the formation of Cooper pairs. Since this phenomenon causes magnetic fields to be expelled in the Meissner effect, materials displaying it trigger levitation. For 10 points, name this phenomenon in which a material displays zero resistance to current. (10[2])■END■ (10[1])
