Quantum computing is one of the most exciting and new scientific disciplines to emerge in the world today. Quantum computers are still a pipe dream, and they are not yet scalable. In this research, an attempt is made to suggest a quantum sequential circuit which is titled as sequential circuits in quantum computing. Quantum D flip-flop, quantum SR latch, quantum SR flip-flop, quantum JK flip-flop, quantum T flip-flop, quantum shift register, quantum ripple counter, and quantum synchronous counters are all examples of sequential circuits.
