100634 - Millisecond lifetimes
N. Lygeros
Millisecond lifetimes and coherence times in 2D transmon qubits.
Materials improvement is a powerful approach to reducing loss and decoherence in superconducting qubits, because such improvements can be readily translated to large-scale processors. Recent work improved transmon coherence by using tantalum as a base layer and sapphire as a substrate.
