TL;DR: In this paper , the authors used the dry etching process of tantalum (Ta) film to obtain transmon qubits with the best lifetime (T1) for multi-qubit fabrication.

TL;DR: Two methods are experimentally demonstrated to directly measure the quantum metric tensor for characterizing the geometry and topology of underlying quantum states in parameter space and a topological phase transition in a simulated time-reversal-symmetric system is explored.
