论文摘要
我们提出了一个简单的方案，用于实施快速任意相位门，并采用脉冲调制以改善与不同噪声源的稳健性。引入了腔的参数驱动以诱导腔与QUTRIT之间的Rabi相互作用，然后通过设计适当的逻辑状态来构建两个Qubit的任意相位门。在此基础上，我们实施了振幅形状的大门，以获得增强的弹性，以控制门时间和频率失调的错误。由于专门设计的逻辑状态，该方案表现出对Qutrits能量松弛的固有阻力。此外，我们表明，通过振幅调制可以显着增强对腔衰减的栅极鲁棒性。
We propose a simple scheme for implementing fast arbitrary phase gates and employ pulse modulation to improve the gate robustness against different sources of noise. Parametric driving of a cavity is introduced to induce Rabi interactions between the cavity and qutrits, and then a two-qubit arbitrary phase gate is constructed by designing proper logical states. On this basis, we implement amplitude-shaped gates to obtain enhanced resilience to control errors in gate time and frequency detuning. By virtue of specifically designed logical states, the scheme displays intrinsic resistance to the energy relaxations of qutrits. Furthermore, we show that the gate robustness against cavity decay can be enhanced significantly with amplitude modulation.
