自然数据的有效量子插值

Efficient quantum interpolation of natural data

Sergi Ramos-Calderer

摘要:

我们提出了有效的方法来插值数据与量子计算机,补充上传技术和量子后处理。量子算法由高效的量子傅里叶变换(QFT)和经典的信号和成像处理技术支持,并为相关数据族打开了量子优势的大门。我们展示了一种QFT插值方法,一种面向自然数据的量子余弦变换(QCT)插值,并且我们通过利用量子电路处理叠加数据的能力来改进它们。提出了一种新型的QCT电路。我们展示了概率分布和量子编码图像的方法,并讨论了由此产生的插值的精度。

英文摘要:

We present efficient methods to interpolate data with a quantum computer that complement uploading techniques and quantum post-processing. The quantum algorithms are supported by the efficient Quantum Fourier Transform (QFT) and classical signal and imaging processing techniques, and open the door of quantum advantage to relevant families of data. We showcase a QFT interpolation method, a Quantum Cosine Transform (QCT) interpolation geared towards natural data, and we improve upon them by utilizing a quantum circuit's capabilities of processing data in superposition. A novel circuit for the QCT is presented. We demonstrate the methods on probability distributions and quantum encoded images, and discuss the precision of the resulting interpolations.
