In this talk, I will present the use of discrete-time quantum walk as an operational tool for developing new protocols and efficient quantum circuits for quantum simulation. I will focus on the simulation of accelerated quantum dynamics and the simulation of Dirac particle dynamics on the near-term quantum hardware. I will also present a new way of realizing universal quantum computation using a single particle quantum walk. For this purpose, we have made use of unique features of the variants of discrete-time quantum walk namely, directed quantum walk, standard quantum walk, and split-step quantum walk.
