The development of quantum algorithms is not a easy task. Elements such as entanglement and quantum paralelism, intrinsics to quantum computation, difficult this task. Quantum walks are crucial tools for development of algorithms, mainly search algorithms. There are many types of quantum walks: with coin toss, Szegedy's, using tessellation (grouping of vertices) and the continuous-time quantum walk. To extract statistics data of a quantum walk, we need to perform its simulation. In this work, we develped the simulator Hiperwalk, a new simulator of quantum walks in graphs of one and two dimension for the quantum walk with a coin toss and coinless using tessellation. The Hiperwalk allows the user to perform simulations of quantum walks in graphs using high performance computing (HPC), even though the user does not knowing parallel programming. The user can employ the parallel devices such as CPU, GPGPU and accelerators cards to speedup the overall process of the walk.
