论文摘要
可以使用Rayleigh-Lorentz不变式分析谐振器的动力学性能，该功能不是精确的常数，但随着时间的推移或多或少而变化。我们研究了通量量子谐振器的这种不变的时间行为，以便更好地理解与谐振器的量子信息检测。通量量子谐振器可用于实施不同的下一代纳米光线和纳米电子设备，例如量子计算系统。通过对不变的时间演化的分析，我们得出了与谐振器最佳绝热量子信息检测的条件。这种情况有助于控制量子共振器的动力学长时间的动力学。在设计用于量子量子态量子态的纳米谐振器时，必须考虑它，这对于量子计算至关重要。
Dynamical properties of a resonator can be analyzed using the Rayleigh-Lorentz invariant which is not an exact constant but varies more or less over time. We investigate the time behavior of this invariant for a flux qubit resonator in order for better understanding of qubit-information detection with the resonator. Flux qubit resonators can be utilized in implementing diverse next generation nano-optic and nano-electronic devices such as quantum computing systems. Through the analyses of the temporal evolution of the invariant, we derive a condition for optimal adiabatic qubit-information detection with the resonator. This condition is helpful for controlling the dynamics of qubit resonators over long periods of time. It is necessary to consider it when designing a nano-resonator used for quantum nondemolition readouts of qubit states, crucial in quantum computation.
