  Over the last few decades,quantum computing(QC)and quantum information processing(QIP)have exploded into a major field of physics,in terms of theory and experimentation extending towards a universal quantum computer as a lasting dream Additionally trapped-ion system is also considered as an ideal platform to investigate the quantum mechanical problems of fundamental nature,due to its decent isolation from exterior,high fidelity manipulation,measurement and extraordinary detection efficiency in c...
