论文摘要
基于量子点的旋转Qubits对电荷噪声有弹性，并且仅受磁噪声影响。但是，环境相互作用会导致这些量子系统的破裂。外部控制参数与破坏的大小直接相关。反过来，这限制了可以用高保真进行操作的那些参数的值范围。在这项工作中，使用量子点旋转量子置量置量系统模型，我们研究了不同的交流磁场对抑制反应性的影响。我们使用我们的技术报告了可用的静态磁场值的可用范围。
Quantum dot-based spin qubits are resilient towards charge noise and are affected by magnetic noise only. However, environmental interaction leads to decoherence in these qubit systems. The external control parameters are directly related to the magnitude of decoherence. This in turn limits the range of values of those parameters for which operations can be done with high fidelity. In this work, using a model of quantum dot spin qubit system, we investigate the impact of varying ac magnetic fields on suppression of decoherence. We report an increment in the usable range of static magnetic field value using our technique.
