Memory-built-in quantum cloning in a hybrid solid-state spin register
Memory-built-in quantum cloning hybrid solid-state spin register
2016/1/22
As a way to circumvent the quantum no-cloning theorem, approximate quantum cloning protocols have received wide attention with remarkable applications. Copying of quantum states to memory qubits provi...
Optimal quantum cloning of orbital angular momentum photon qubits via Hong-Ou-Mandel coalescence
Optimal quantum cloning orbital angular momentum photon via Hong-Ou-Mandel coalescence
2010/11/8
The orbital angular momentum (OAM) of light, associated with a helical structure of the wavefunction, has a great potential for quantum photonics, as it allows attaching a higher dimensional quantum s...
Linear amplification and quantum cloning for non-Gaussian continuous variables
Linear amplification quantum cloning non-Gaussian continuous variables
2010/10/19
We investigate phase-insensitive linear amplification at the quantum limit for single- and two-mode states and show that there exists a broad class of non-Gaussian states whose nonclassicality survive...
