摘要
In this study, we show that one cannot use non-local resources for probabilistic signalling even if one can delete a quantum state with the help of a probabilistic quantum deletion machine (PQDM). Here, we find that PQDM is not going to help us in identifying two statistical mixtures at a remote location. Also we derive the bound on deletion probability from a no-signalling condition.
