Realization of scalable quantum computing device has foundational importance of demonstrating quantum speedup in actual problem solving, as well as several known practical applications. In contrast to the rapid advances in theory, the frontier of experimental effort of building a quantum computer of significant size still faces a wide range of technological challenges. The experimental demonstrations so far have been limited to only small sized computers,. Architectures for constructing large-scale quantum processors have been considered and one can readily estimate the performance of these systems by simulating quantum circuit on the hardware.
