Abstract

We have experimentally demonstrated polarization entanglement using continuous variables in an ultra-short pulsed laser system at the telecommunications wavelength of 1.5 μm. Exploiting the Kerr non-linearity of a glass fibre we generated polarization squeezed pulses with Ŝ2 as the only non-zero Stokes parameter, thus Ŝ1 and Ŝ3 being the conjugate pair. Polarization entanglement was generated by interference of the polarization squeezed field with a vacuum on a 50:50 beamsplitter. The two resultant beams exhibit strong quantum noise correlations in Ŝ1 and Ŝ3. The sum noise signal of Ŝ3 was at the respective shot noise level and the difference noise signal of Ŝ1 fell -2.9 dB below this value.
