    "abstract": "It is known that the stronger no-cloning theorem and the no-deleting theorem\ntaken together provide the permanence property of quantum information. Also, it\nis known that the violation of the no-deletion theorem would imply signalling.\nHere, we show that the violation of the stronger no-cloning theorem could lead\nto signalling. Furthermore, we prove the stronger no-cloning theorem from the\nconservation of quantum information. These observations imply that the\npermanence property of quantum information is connected to the no-signalling\nand the conservation of quantum information.",
