Universal Quantum Cloning Machines for Two Identical Mixed Qubits

We present a series of universal quantum cloning machines for two identical mixed qubits. Every machine is optimal in the sense that it achieves the optimal bound of the single copy shrinking factor.…

Optimal probabilistic cloning and purification of quantum states

The examples reveal that the probabilistic cloner may yield higher fidelity than the best deterministic cloner even when the states that should be cloned are linearly dependent and are drawn from a continuous set.

Experimental demonstration of entanglement-enabled universal quantum cloning in a circuit

No-cloning theorem forbids perfect cloning of an unknown quantum state. A universal quantum cloning machine (UQCM), capable of producing two copies of any input qubit with the optimal fidelity, is of…

Optimal quantum cloning and universal NOT without quantum gates

Abstract We present ways of realizing quantum cloning via stimulated emission. Universality of the cloning procedure is achieved by choosing systems that have appropriate symmetries. We first discuss…

Universal asymmetric quantum cloning revisited

The bipolar theorem is used, a famous method from convex analysis, to completely characterise the set of achievable single quantum clone qualities using the fidelity as the authors' figure of merit; from this it is easier to give the optimal cloning map and to quantify the quality tradeoff in universal asymmetric quantum cloning.

Universal Optimal Cloning of Qubits and Quantum Registers

The machine which universally clones states of quantum objects in arbitrary-dimensional Hilbert spaces is presented, and universal cloning of quantum registers is discussed.

Manipulating quantum information via quantum cloning

An extensive characterization of the information flux underlying the  universal cloning process is presented together with the realization of several cloning and measurement tasks. The restoration of…

General sequential quantum cloning

Some multipartite quantum states can be generated in a sequential manner which may be implemented by various physical setups such as microwave and optical cavity QED, trapped ions, quantum dots, etc.…

Applications of quantum cloning

Quantum Cloning Machines (QCMs) allow for the copying of information, within the limits imposed by quantum mechanics. These devices are particularly interesting in the high-gain regime, i.e., when…

How well can one copy an arbitrary qubit? To answer this question we consider two arbitrary vectors in a two-dimensional state space and an abstract copying transformation which will copy these two…

Quantum copying: A network

We present a network consisting of quantum gates that produces two imperfect copies of an arbitrary qubit. The quality of the copies does not depend on the input qubit. We also show that for a…

Broadcasting of entanglement via local copying

We show that inseparability of quantum states can be partially broadcasted (copied or cloned) with the help of local operations, i.e., distant parties sharing an entangled pair of spin-1/2 states can…
