论文摘要
在这项工作中，我们提出了一种在量子计算的背景下执行算法分化的算法。我们提出了两个版本的算法，一种是完全量子的，一个是雇员的经典步骤（混合方法）。由于在量子计算机上已经实现了基本功能的实现，因此我们建议的方案很容易应用。此外，由于某些步骤（例如CNOT运算符）在量子计算机上的某些步骤比在经典计算机上可以（或将会更快），因此我们的过程最终可能证明量子算法差异化相对于其经典对应物具有优势。
In this work we present an algorithm to perform algorithmic differentiation in the context of quantum computing. We present two versions of the algorithm, one which is fully quantum and one which employees a classical step (hybrid approach). Since the implementation of elementary functions is already possible on quantum computers, the scheme that we propose can be easily applied. Moreover, since some steps (such as the CNOT operator) can (or will be) faster on a quantum computer than on a classical one, our procedure may ultimately demonstrate that quantum algorithmic differentiation has an advantage relative to its classical counterpart.
