论文摘要
处理数据的新兴量子算法要求将经典输入数据表示为量子状态。这些数据处理算法通常遵循量子计算的门模型(要求将Qubits初始化为基础状态,通常为$ \ lvert 0 \ rangle $),因此经常采用状态生成电路将初始化的基础状态转换为数据代表状态。有很多方法可以用量子数据编码经典数据,并且基础编码的经常应用方法不允许在其他变体中进行优化。因此,在这项工作中,我们考虑自动合成可寻址,量子读取的内存(QROM)电路,它们充当数据编码的状态生成电路。我们研究了三种数据编码方法,其中一种介绍以提供改进的动态范围和精度。我们提出了将这些编码方法比较QROM合成的实验结果,以更好地理解每个编码的含义和应用的含义和应用。
Emerging quantum algorithms that process data require that classical input data be represented as a quantum state. These data-processing algorithms often follow the gate model of quantum computing--which requires qubits to be initialized to a basis state, typically $\lvert 0 \rangle$--and thus often employ state generation circuits to transform the initialized basis state to a data-representation state. There are many ways to encode classical data in a qubit, and the oft-applied approach of basis encoding does not allow optimization to the extent that other variants do. In this work, we thus consider automatic synthesis of addressable, quantum read-only memory (QROM) circuits, which act as data-encoding state-generation circuits. We investigate three data encoding approaches, one of which we introduce to provide improved dynamic range and precision. We present experimental results that compare these encoding methods for QROM synthesis to better understand the implications of and applications for each.
