Duplicating classical bits with universal quantum cloning machine
It seems there is a large gap between quantum cloning and classical duplication since quantum mechanics forbid perfect copies of unknown quantum states. In this paper, we prove that a classical
Distribution of quantum Fisher information in asymmetric cloning machines
TLDR
It is found that any asymmetric cloning outperforms symmetric cloning on the distribution of QFI for d ≤ 18, whereas some but not all asymmetric clones strategies could be worse than symmetric ones when d > 18.
Cloning of Quantum Entanglement.
TLDR
Results show that one maximally entangled photon pair can be broadcast into two entangled pairs, both with state fidelities above 50%.
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
Existence and construction of simultaneous cloning machines for mixed states
It is a well-known fact that the no-cloning theorem forbids the creation of identical copies of an arbitrary unknown quantum state. In other words, there does not exist a quantum cloning machine that
Optimal phase cloning machine in a three‐dimensional transmon qubit system
In quantum mechanics, although the no‐cloning theorem forbids us to clone an arbitrary quantum state ideally, it is still possible to partially reproduce an unknown quantum state by using a phase
Quantum deleting and cloning in a pseudo-unitary system
In conventional quantum mechanics, quantum no-deleting and no-cloning theorems indicate that two different and nonorthogonal states cannot be perfectly and deterministically deleted and cloned,

TLDR
An experiment is reported that realizes cloning of quantum states from an electron spin to a nuclear spin in a hybrid solid-state spin register with near-optimal fidelity.
The roles of quantum correlations in quantum cloning
In this paper, we study the entanglement and quantum discord of the output modes in the unified 1 → 2 state-dependent cloning and probabilistic quantum cloning. The tripartite entanglement among the
Process-optimized phase-covariant quantum cloning
TLDR
The optimal global fidelity for phase-covariant cloning machines via semi-definite programming optimization is computed, thereby completing a remaining gap in the previous results on QCMs.

Hybrid Quantum Cloning Machine
TLDR
The introduced Hybrid quantum cloning machine or transformation is nothing but a combination of pre-existing quantum cloning transformations and creates its own identity in the field of quantum cloners.
Quantum cloning
The impossibility of perfectly copying or cloning an unknown quantum state is one of the basic rules governing the physics of quantum systems. The processes that perform the optimal approximate
Implementation of optimal phase-covariant cloning machines
TLDR
The theory of cloning is rendered a fundamental tool for the analysis of the security of quantum cryptographic protocols, for the distribution of quantum information to many partners, and for the transmission of information contained in a system into correlations between many systems.
