Abstract

Josephson traveling wave parametric amplifiers can have high gain and wide frequency range, high sensitivity, and low noise, which makes them promising for quantum computing, array receiver readout systems, spectroscopy, single-photon detectors, etc. In this paper, the authors investigate samples of traveling wave parametric amplifiers based on a three-layer Nb/AlO_x/Nb superconductor–insulator–superconductor (SIS) structure with a SNAIL (Superconducting Nonlinear Asymmetric Inductive Elements) series array. Each SNAIL cell consists of the kinetic inductance of four SIS junctions and the nonlinear inductance of a smaller SIS junction. The cells are alternately connected in antiphase with respect to the magnetic flux, which ensures a change in the sign of the Kerr nonlinearity and a reduction in the phase mismatch for the pump frequency, signal frequency, and idler frequency. The transmission spectra of the samples were measured at temperatures of 4.2 and 2.8 K in the frequency range of 0.1–6 GHz.

四光子约瑟夫逊行波参量放大器

约瑟夫森行波参量放大器具有高增益、宽频率范围、高灵敏度、低噪声等特点，在量子计算、阵列接收机读出系统、光谱学、单光子探测器等领域具有广阔的应用前景。本文研究了基于三层Nb/AlOx/Nb超导体-绝缘体-超导体（SIS）结构的行波参量放大器样品，该结构采用了超导非线性不对称电感元件（SNAIL）系列阵列。每个SNAIL细胞由四个SIS结的动态电感和一个较小SIS结的非线性电感组成。相对于磁通量，电池以反相位交替连接，这确保了克尔非线性符号的变化，并减少了泵频、信号频率和空转频率的相位不匹配。在0.1-6 GHz频率范围内，测量了样品在4.2和2.8 K温度下的透射光谱。
