Quantum state transfer between two photons with polarization and orbital angular momentum via quantum teleportation technology

چکیده
Quantum teleportation is a useful quantum information technology to transmit states between different degrees of freedom. Here we report state transfer experiment in the linear optical system, transferring single-photon polarization degree freedom (DoF) another photon orbital angular momentum (OAM) via biphoton OAM entangled channel. Our experimental method based on technology. The differences ours and original scheme that known ours, our for particles with DoFs, while one same DoF. In addition, present implemented high Bell efficiency since each four hybrid-entangled can be discriminated. We use six poles Bloch sphere test experiment, fidelity $91.8\ifmmode\pm\else\textpm\fi{}1.3%$.

Quantum field theory of photons with orbital angular momentum
A quantum-field-theory approach is put forward to generalize the concept of classical spatial light beams carrying orbital angular momentum to the single-photon level. This quantization framework is carried out both in the paraxial and nonparaxial regimes. Upon extension to the optical phase space, closed-form expressions are found for a photon Wigner representation describing transformations o...
متن کاملPolarization control of single photon quantum orbital angular momentum states.
The orbital angular momentum of photons, being defined in an infinite-dimensional discrete Hilbert space, offers a promising resource for high-dimensional quantum information protocols in quantum optics. The biggest obstacle to its wider use is presently represented by the limited set of tools available for its control and manipulation. Here, we introduce and test experimentally a series of sim...
متن کاملQuantum Formulation of Fractional Orbital Angular Momentum
The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to noninteger values of the orbital angular momentum. This requires the introduction of an additional parameter, the orientation of a phase discontinuity associated with fractional values of the orbital angular momentum. We apply our formalism to the propagation of light modes...
متن کاملQuantum Router for Single Photons Carrying Spin and Orbital Angular Momentum
Quantum router is an essential element in the quantum network. Here, we present a fully quantum router based on interaction free measurement and quantum dots. The signal photonic qubit can be routed to different output ports according to one control electronic qubit. Besides, our scheme is an interferometric method capable of routing single photons carrying either spin angular momentum (SAM) or...
متن کاملOrbital angular momentum of entangled counterpropagating photons.
We elucidate the paraxial orbital angular momentum of entangled photon pairs generated by spontaneous parametric downconversion in different noncollinear geometries in which the entangled photons counterpropagate. We find, in particular, the orbital angular momentum of entangled pairs generated in transverse-emitting configurations, in which none of the known rules for selecting orbital angular...
