Before revision: Recent work has shown significantly improved T1 times as long as 95 μs by replacing the superconducting transmission line cavity with a three-dimensional superconducting cavity .
After revision: , and by replacing niobium with tantalum in the transmon device, T1 is further improved up to 0.3 msRecent work has shown significantly improved T1 times as long as 95 μs by replacing the superconducting transmission line cavity with a three-dimensional superconducting cavity .
