2D transmons with lifetimes and coherence times exceeding 1 millisecond Materials improvements are a powerful approach to reducing loss and decoherence in superconducting qubits because such improvements can be readily translated to large scale processors. Recent work imp...

Our paper that tells you how to make millisecond transmons just appeared. Congrats Matthew, Faranak, and team! In collaboration with Nathalie de Leon and Bob Cava, and building on five years of work in C2QA, one of the five DOE National Quantum Initiative Centers.
