چکیده
Remote state preparation (RSP) provides a useful way of transferring quantum information between two distant nodes based on the previously shared entanglement. In this paper, we study RSP an arbitrary single-photon in degrees freedom (DoFs). Using hyper-entanglement as resource, our first goal is to remotely prepare polarization and frequency DoFs second one reconstruct time-bin DoFs. process, sender will rotate each DoF photon according knowledge be communicated. By performing projective measurement sender’s photon, original can reconstructed at receiver’s systems. This work demonstrates novel capability for longdistance communication.

Remote preparation of single-photon "hybrid" entangled and vector-polarization States.
Quantum teleportation faces increasingly demanding requirements for transmitting large or even entangled systems. However, knowledge of the state to be transmitted eases its reconstruction, resulting in a protocol known as remote state preparation. A number of experimental demonstrations to date have been restricted to single-qubit systems. We report the remote preparation of two-qubit "hybrid"...
متن کاملSpectral engineering of entangled two-photon states
We experimentally demonstrate an approach for manipulating the spectral profiles of entangled-photon pairs. The spectral properties are determined by selecting both the appropriate spatial profile of the pump laser radiation and the geometry of the noncollinear spontaneous parametric downconversion. Both spectra, the spectrum of the individual signal and idler photons, and the joint spectrum of...
متن کاملComplete Positivity and Entangled Degrees of Freedom
We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in presence of a gaussian stochastic background. We show that physical consistency requires the resulting markovian dissipative time-evolution to be completely positive.
متن کاملRemote preparation and distribution of bipartite entangled states.
We prove a powerful theorem for tripartite remote entanglement distribution protocols that establishes an upper bound on the amount of entanglement of formation that can be created between two single-qubit nodes of a quantum network. Our theorem also provides an operational interpretation of concurrence as a type of entanglement capacity.
متن کاملRemote state preparation: arbitrary remote control of photon polarization.
We experimentally demonstrate the first remote state preparation of arbitrary single-qubit states, encoded in the polarization of photons generated by spontaneous parametric down-conversion. Utilizing degenerate and nondegenerate wavelength entangled sources, we remotely prepare arbitrary states at two wavelengths. Further, we derive theoretical bounds on the states that may be remotely prepare...
