Abstract

In this paper the parallel algorithms to simulate measurements and unitary operations in the quantum computing model are presented. The proposed solutions are implemented using the CUDA technology. Moreover, a more effective routine for processing density matrices is presented. The main advantages of this approach are the reduced memory requirement and a good use of the computing power of the GPU hardware. Additionally, the proposed solution can be used to simulate circuits build from qubits or qudits.
