Quantum deletion: Beyond the no-deletion principle
Suppose we are given two identical copies of an unknown quantum state and we wish to delete one copy from among the given two copies. The quantum no-deletion principle restricts us from perfectly deleting a copy but it does not prohibit us from deleting a copy approximately. Here we construct two types of a “ universal quantum deletion machine” which approximately deletes a copy such that the f...
متن کاملSentence Compression Beyond Word Deletion
In this paper we generalise the sentence compression task. Rather than simply shorten a sentence by deleting words or constituents, as in previous work, we rewrite it using additional operations such as substitution, reordering, and insertion. We present a new corpus that is suited to our task and a discriminative tree-totree transduction model that can naturally account for structural and lexi...
متن کاملQuantum deletion is possible
A deleting operation is introduced which differs from the commonly used controlled-not (C-not) conditional logical operation −to flip the (classical or quantum) state of the last copy in a chain in a deletion process. It is completely reversible, in the classical case, possessing a most natural cloning operation counterpart. We call this deleting procedure R-deletion since, in a way, it can be ...
متن کاملProbabilistic exact deletion and probabilistic no-signalling
In this work we show that one cannot use non-local resources for probabilistic signalling even if one can delete a quantum state with the help of probabilistic quantum deletion machine. Here we find that probabilistic quantum deletion machine is not going to help us in identifying two statistical mixture at remote location. Also we derive the bound on deletion probability from no-signalling con...
متن کاملQuantum copying: Beyond the no-cloning theorem.
We analyze a possibility of copying (≡ cloning) of arbitrary states of quantum-mechanical spin1/2 system. We show that there exists a “universal quantum-copying machine” (i.e. transformation) which approximately copies quantum-mechanical states such that the quality of its output does not depend on the input. We also examine a machine which combines a unitary transformation and a selective meas...
