Design of A Hardware Description Language Based Quantum Circuit Simulator

Quantum theory of computation establishes that there are problems for which quantum algorithms are far more efficient than their classical counterpart. Advances in quantum computing have initiated the design of systems based on quantum logic gates. Quantum computer hardware being primarily available in research laboratories at present, it mandates the ability to design, develop and test quantum logic operations by simulation of quantum logic circuits on classical computers. In this paper, we have defined a programming model for the design of a quantum circuit simulator, which can simulate a given quantum circuit obeying the rules of quantum gate operations. The quantum gate operations on both pure and superposed quantum states are being done with the help of effective data structures. The proposed quantum circuit simulator also incorporates the simulation of quantum circuit error under the action of certain quantum faults.
