Monoidal categories allow a binary operation, often called a tensor product, among objects. Monoidal categories have been used in many areas of mathematics. Today, monoidal categories and their impressive pictorial representations are extensively used in research and application areas such as quantum computing [1], topological field theory [2], natural language processing [3], and other emerging areas. Many introductory articles and textbooks on monoidal categories are available today. So, learners have greater choice.
