摘要:

基于三波混频的参量转换和放大是实现高效量子操作的重要手段。对于超导量子比特,这样的操作可以用四极约瑟夫森结元件实现,约瑟夫森环调制器(JRM),其表现为无损耗的三波混频器。然而,组合多个四极元件是困难的任务,因此具有纯三波偶极元件将是有利的,该纯三波偶极元件可以被镶嵌以增加功率处理和/或信息吞吐量。在这里,我们提出了一个三阶非线性偶极子电路元件,实现三波混频。基于所提出的纯三阶非线性非简并放大器的实验结果报告。

英文摘要:

Parametric conversion and amplification based on three-wave mixing are powerful primitives for efficient quantum operations. For superconducting qubits, such operations can be realized with a quadrupole Josephson junction element, the Josephson Ring Modulator (JRM), which behaves as a loss-less three-wave mixer. However, combining multiple quadrupole elements is a difficult task so it would be advantageous to have a pure three-wave dipole element that could be tessellated for increased power handling and/or information throughput. Here, we present a dipole circuit element with third-order nonlinearity, which implements three-wave mixing. Experimental results for a non-degenerate amplifier based on the proposed pure third-order nonlinearity are reported.
