Abstract

It is known that if one could clone an arbitrary quantum state one could send signal faster than the speed of light. However it remains interesting to see that if one can perfectly self replicate an arbitrary quantum state, does it violate the no signalling principle? Here we see that perfect self replication would also lead to superluminal signalling.

Why This Paper Matters

  • It adds a 2007 reference point for readers tracking recent quantum research.
  • It is known that if one could clone an arbitrary quantum state one could send signal faster than the speed of light.
