高动态电感NbN纳米线超电感
High Kinetic Inductance NbN Nanowire Superinductors
摘要：
我们证明了高动力学电感无序超导体可以实现低微波损耗，非耗散电路元件的阻抗大于量子电阻（$R_Q = h/4e^2 \simeq 6.5kΩ$）。这种元件被称为超级电感器，可以产生一个量子线路，其中电荷波动被抑制。该超电感由40 nm宽的氮化铌纳米线组成，并表现出$2.5 \times 10^4$的单光子品质因数。此外，通过检查损耗率，我们证明了我们的纳米线器件的耗散可以完全理解的两级系统损耗的框架。
英文摘要：
We demonstrate that a high kinetic inductance disordered superconductor can realize a low microwave loss, non-dissipative circuit element with an impedance greater than the quantum resistance ($R_Q = h/4e^2 \simeq 6.5kΩ$). This element, known as a superinductor, can produce a quantum circuit where charge fluctuations are suppressed. The superinductor consists of a 40 nm wide niobium nitride nanowire and exhibits a single photon quality factor of $2.5 \times 10^4$. Furthermore, by examining loss rates, we demonstrate that the dissipation of our nanowire devices can be fully understood in the framework of two-level system loss.
