Quantum-circuit processor (QCP) is a parallel processor that executes quantum algorithms at a processing speed comparable to a quantum computer. The QCP emulates the quantum superposition, utilizing massive silicon devices in the fractal hardware-architecture. Its design cost is relaxed due to that recursive structure although a huge amount of devices are required for it. In this paper, 8-qubit QCP was fabricated within a programmable logic device. This is the first realization of the 8-qubit-hardware quantum computing as far as we know. A factoring algorithm is demonstrated by using it in this paper.
