Reducing TLS loss in tantalum CPW resonators using titanium sacrificial layers
Zachary Degnan, Chun-Ching Chiu, Yi-Hsun Chen +5
We demonstrate a substantial reduction in two-level system loss in tantalum coplanar waveguide resonators fabricated on high-resistivity silicon substrates through the use of an ul…

Using coherent feedback for a periodic clock
Stefan Zeppetzauer, Leonardo Assis Morais, Xin He +2
A driven linear oscillator and a feedback mechanism are two necessary elements of any classical periodic clock. Here, we introduce a novel, fully quantum clock using a driven oscil…
