Asymptotic quantum cloning is state estimation.
The impossibility of perfect cloning and state estimation are two fundamental results in quantum mechanics. It has been conjectured that quantum cloning becomes equivalent to state estimation in the asymptotic regime where the number of clones tends to infinity. We prove this conjecture using two known results of quantum information theory: the monogamy of quantum correlations and the propertie...
متن کاملIs Global Asymptotic Cloning State Estimation?
We investigate the asymptotic relationship between quantum cloning and quantum estimation from the global point of view where all the copies produced by the cloner are considered jointly. For an N -to-M cloner, we consider the overall fidelity between the state of theM output systems and the state ofM ideal copies, and we ask whether the optimal fidelity is attained by a measureand-prepare prot...
متن کاملAsymptotic Estimation of Shift Parameter of a Quantum State∗
The rise of quantum estimation theory dates back to the late 1960s – 1970s (see [8], [9]). It was initially developed as an adequate mathematical framework for design of optimal receiver in quantum communication channels, and later turned out to be relevant also for clarification of some foundational issues of quantum measurement. New interest to quantum estimation theory was brought by the dev...
متن کاملNash equilibria in quantum state estimation and cloning games
We apply a generalized quantum game formalism to the phenomena of quantum cloning and quantum state estimation. We find that both phenomena can be usefully viewed as quantum games. We compute the corresponding Nash equilibria and payoffs for both phenomena. Our work also provides a new perspective on quantum cryptography. [email protected] [email protected]
متن کاملGame-theoretic discussion of quantum state estimation and cloning
We present a game-theoretic perspective on the problems of quantum state estimation and quantum cloning. This enables us to show why the focus on universal machines and the different measures of success, as employed in previous works, are in fact legitimite. [email protected] [email protected]
