OWQS: One-Way Quantum Computation Simulator

In one-way quantum computation (1WQC) model, universal quantum computations are performed using measurements to designated qubits in a highly entangled state. The choices of basis for these measurements as well as the structure of the entanglements specify a quantum algorithm. Although a number of methods have been proposed to simulate quantum circuit model on classical computers, no efficient tool has been developed to simulate the 1WQC model directly. In this paper, some techniques such as qubit elimination, implicit and in-place matrix-vector multiplication and pattern reordering are utilized to considerably reduce the time and memory needed for the simulations. These techniques were implemented in a tool called One-Way Quantum computation Simulator (OWQS). Experimental results validate the efficiency of the proposed approach.
