Why Aluminum, Niobium, and Tantalum Decide the Fate of Superconducting Quantum Computers
Aluminum, niobium, and tantalum are the key superconducting materials dictating the performance of quantum computers by mitigating decoherence. Recent breakthroughs in qubit coherence times, exceeding 1 millisecond, are attributed to material innovation, particularly with tantalum, rather than new qubit designs.
