I teleported home one nightQuantum teleporter creates laser beam clones

As science fiction writers realised about ten years ago, if you teleport something you make a copy of it, you don't translate it from the place of origin to the destination. And the bits can get muddled up on the way. This could create some interesting ethical dilemmas. If you delete the original and retain the copy, is that murder? This problem is dealt with in a novel way in Empire of Bones by Liz Williams.
