Newfound Superconductor material could be the ‘Silicon of Quantum Computers’

A cartoon of two islands in a blue sea. Each island has mountains and explorers. At bottom are clouds and a pot of gold.
We have already found lots of superconductors, but this whimsical illustration shows why one superconductor’s newfound properties may make it especially useful. Most known superconductors are spin singlets, found on the island to the left. Uranium ditelluride, however, is a rare spin triplet, found on the island to the right, and also exists at the top of a mountain representing its unusually high resistance to magnetic fields. These properties may make it a good material for making qubits, which could maintain coherence in a quantum computer despite interference from the surrounding environment.
