    Notes: [Auszug] Quantum cryptography makes use of the unusual properties of quantum mechanics to protect encoded information. In trying to listen in on a message sent through a properly designed quantum communication channel, an eavesdropper will inevitably disturb the signal and thereby reveal his or her ...

    Quantum disentanglement and phase measurements (1995)

    Notes: Abstract A 50∶50 beam splitter disentangles a two-mode squeezed vacuum state into two single-mode squeezed vacuum states. With the proper choice of parameters these two single-mode states will be identical. If one is passed through a device which shifts its phase, then the phases of the shifted and reference (unshifted) modes can be determined by the Vogel-Schleich technique [Phys. Rev. A44 (1991) 7642]. In this way the phase difference, i.e. the phase shift, can be measured to an accuracy of 1/N, whereN is the total number of photons coming into the beam splitter. We also propose an improved scheme involving the disentanglement of a shifted two-mode squeezed vacuum state. This leads to two shifted squeezed vacaum states at the output of the beam splitter. If one of these is passed through the phase shifter, then by performing homodyne measurements on the shifted and unshifted modes the phase shift can again be determined to an accuracy of 1/N.
