Query: A note on superposition of two unknown states using Deutsch CTC model   In a recent work, authors prove a yet another no-go theorem that forbids the
existence of a universal probabilistic quantum protocol producing a
superposition of two unknown quantum states. In this short note, we show that
in the presence of closed time like curves, one can indeed create superposition
of unknown quantum states and evade the no-go result.
