Optimal Quantum Cloning Machines
We present Quantum Cloning Machines (QCM) that transform N identical qubits into M > N identical copies and we prove that the fidelity (quality) of these copies is optimal. The connection between cloning and measurement is discussed in detail. When the number of clones M tends towards infinity, the fidelity of each clone tends towards the optimal fidelity that can be obtained by a measurement o...
متن کاملQuantum cloning machines with phase-conjugate input modes.
A quantum cloning machine is introduced that yields M identical optimal clones from N replicas of a coherent state and N' replicas of its phase conjugate. It also optimally produces M' = M+N'-N phase-conjugate clones at no cost. For well chosen ratios N'/N, this machine is shown to provide better cloning fidelities than the standard (N+N')-->M cloner. The special cases of the optimal balanced c...
متن کاملQuantum cloning machines for equatorial qubits
Quantum cloning machines for equatorial qubits are studied. For 1 to 2 phase-covariant quantum cloning machine, using Hilbert-Schmidt norm and Bures fidelity, we show that our transformation can achieve the bound of the fidelity. Networks consisting of quantum gates are presented to realize the quantum cloning transformations. The copied equatorial qubits are shown to be separable by using Pere...
متن کاملQuantum Cloning Machines of d-level System
No-cloning theorem is one of the most fundamental differences between classical and quantum information theories. It tells us that an unknown quantum state can not be copied perfectly[1]. This no-cloning theorem has important consequences for the whole quantum information processing[2]. However, no-cloning theorem does not forbid imperfect cloning, and it is interesting to know how well we can ...
متن کاملQuantum-enhanced metrology for multiple phase estimation with noise
We present a general quantum metrology framework to study the simultaneous estimation of multiple phases in the presence of noise as a discretized model for phase imaging. This approach can lead to nontrivial bounds of the precision for multiphase estimation. Our results show that simultaneous estimation (SE) of multiple phases is always better than individual estimation (IE) of each phase even...
