论文摘要
具有适度的自由度的量子系统的精确控制，在量子技术中的应用中感兴趣，在实验上是可行的。在科学文献中，正在广泛讨论各种类型的量子场景和协议。我们建议，分析和优化一项协议，该协议允许快速模拟未知量子状态的属性，这些量子状态依靠最小相关信息。我们的协议具有具有量子识别和绝热捷径的共同特征，允许避免正交性灾难，在物理上非常相似的系统之间的过渡以零或非常低的保真度为特征。
Precise control of quantum systems with a moderate number of degrees of freedom, being of interest for application in quantum technologies, becomes experimentally feasible. Various types of quantum scenarios and protocols are being widely discussed in scientific literature. We propose, analyze, and optimize a protocol which allows fast simulation of properties of unknown quantum states relying on minimum relevant information. Our protocol, having common features with quantum identification and shortcuts to adiabaticity, permits avoiding orthogonality catastrophe, where transitions between physically very similar systems are characterized by zero or a very low fidelity.
