A Simple Question, Complex Answer: Quantum Multiplication Algorithms

The efficient multiplication of large numbers has been a long-standing challenge in classical computation and has been extensively studied for decades. It seems that the existing classical algorithms are close to their theoretical limit and offer little room for further improvement. However, with the advent of quantum computers and the need for quantum algorithms that can perform multiplication on quantum hardware, a new paradigm emerges. In this presentation, after reviewing classical multiplication algorithms, we introduce quantum versions of them. Finally, we present a quantum multiplication algorithm that can leverage quantum resources to perform multiplication with advantages over modern classical multiplication algorithms.
