Entanglement concentration after a multi-interactions channel
Eleonora Nagali, Fabio Sciarrino, Francesco De Martini +2
Different procedures have been developed in order to recover entanglement after propagation over a noisy channel. Besides a certain amount of noise, entanglement is completely lost…
Quantum information transfer from spin to orbital angular momentum of photons
Eleonora Nagali, Fabio Sciarrino, Francesco De Martini +4
The optical "spin-orbit" coupling occurring in a suitably patterned nonuniform birefringent plate known as `q-plate' allows entangling the polarization of a single photon with its…
Entanglement-Seeded-Dual Optical Parametric Amplification: Applications to Quantum Communication, Imaging, and Metrology
Ryan T. Glasser, Hugo Cable, Jonathan P. Dowling +3
The study of optical parametric amplifiers (OPAs) has been successful in describing and creating nonclassical light for use in fields such as quantum metrology and quantum lithogra…
