On the Realization of quantum gates coming from the Tracy-Singh product

TL;DR

This paper investigates how to realize quantum gates formed via the Tracy-Singh product, focusing on their construction from local and universal gates, especially when originating from Yang-Baxter gates.

Contribution

It provides a method to realize Tracy-Singh product-based gates using local and universal gates, expanding understanding of their implementation in quantum computing.

Findings

The Tracy-Singh product preserves the Yang-Baxter property.

Entangling properties are maintained under the Tracy-Singh product.

A realization scheme for these gates in terms of local and universal gates is described.

Abstract

The Tracy-Singh product of matrices permits to construct a new gate $c \boxtimes c'$ from two $2$-qudit gates $c$ and $c'$. If $c$ and $c'$ are both Yang-Baxter gates, then $c \boxtimes c'$ is also a Yang-Baxter gate, and if at least one of them is entangling, then $c \boxtimes c'$ is also entangling. A natural question arises about the realisation of these gates, $c \boxtimes c'$, in terms of local and universal gates. In this paper, we consider this question and describe this realisation.
