Abstract

This study is devoted to the investigation of the Josephson phase qubit spectrum considering the anharmonic current-phase relation of the junction. The change in energy difference in the spectrum of phase qubits based on single-band/multiband Josephson junctions is also analyzed. It was shown that the presence of the anharmonic term in the current-phase relation and frustration effects in the junction electrodes leads to changing effective plasma frequencies in the different cases and results in an energy spectrum.

非谐波和受挫效应对约瑟夫森相位量子比特特性的影响
本文研究了考虑非谐波电流-相位关系的Josephson相位量子比特谱。分析了基于单带/多带约瑟夫森结的相位量子比特谱能差的变化。结果表明,电流相关系中的非调和项和结电极中的挫折效应会导致不同情况下有效等离子体频率的变化,从而产生能谱。
