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...

We suggest a tunable optical device to synthesize Fock states and their superpositions starting
from a coherent source. The scheme involves an avalanche triggering photodetector and a ring
cavity co...
