Non-volatile device is proposed in this article based on quantum-dot cellular automata architecture, which will be efficiently useful as a binary qubit system. In standards, today's theoretical researches are going on the volatile QCA gates, which are efficient well in performance towards the rapid binary data computation. However, what if it can store some data for a while. ? Therefore, a novel methodology has been proposed theoretically towards the non-volatility of the QCA cells. As expected that this gate would be able to exhibit the non-volatility.
