    "abstract": "In this work, we design a deleting machine and shown that for some given\ncondition on machine parameters, it gives slightly better result than P-B\ndeleting machine [5,6]. Also it is shown that for some particular values of the\nmachine parameters it acts like Pati-Braunstein deleting machine. We also study\nthe combined effect of cloning and deleting machine, where at first the cloning\nis done by some standard cloning machines such as Wootters-Zurek [1] and\nBuzek-Hillery [2] cloning machine and then the copy mode is deleted by\nPati-Braunstein deleting machine or our prescribed deleting machine. After that\nwe examine the distortion of the input state and the fidelity of deletion .",
