Nonlinear qubit master equations have recently been shown to exhibit rich dynamical phenomena such as period doubling, Hopf bifurcation, and strange attractors usually associated with classical nonlinear systems. Here we investigate nonlinear qubit models that support tunable Lorenz attractors. A Lorenz qubit could be realized experimentally by combining qubit torsion, generated by real or simulated mean field dynamics, with linear amplification and dissipation. This would extend engineered Lorenz systems to the quantum regime, allowing for their direct experimental study and possible application to quantum information processing.
最近研究发现，非线性量子比特主方程展现出丰富的动力学现象，如倍周期、霍普夫分岔以及通常与经典非线性系统相关的奇怪吸引子。在此，我们研究支持可调谐洛伦兹吸引子的非线性量子比特模型。通过将由真实或模拟平均场动力学产生的量子比特扭转与线性放大及耗散相结合，洛伦兹量子比特可通过实验实现。这将把人工构建的洛伦兹系统扩展到量子领域，使其能够直接进行实验研究，并有可能应用于量子信息处理。
