Entangling Different Degrees of Freedom by Quadrature Squeezing Cylindrically Polarized Modes [PDF]

Physical Review Letters, 2011
Quantum systems such as, for example, photons, atoms, or Bose-Einstein condensates, prepared in complex states where entanglement between distinct degrees of freedom is present, may display several intriguing features. In this Letter we introduce the concept of such complex quantum states for intense beams of light by exploiting the properties of ...

Efficient polarization qubit transmission assisted by frequency degree of freedom [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2011
We present an efficient arbitrary polarization qubit transmission scheme against channel noise by utilizing frequency degree of freedom, which is more stable in transmission surroundings. The information of quantum state is encoded in frequency state during the transmission and transferred to polarization state later. Both the fidelity of quantum state
