Information losses in continuous-variable quantum teleportation
Quantum teleportation allows the transmission of an unknown quantum state by combining the nonlocal quantum coherence of entangled states with the transmission of classical information obtained in a joint measurement of the unknown input state and one part of the entangled pair @1#. Ideally, the classical information transmitted contains no information about the input state, and the output stat...
متن کاملTeleportation using continuous variable quantum cloning machine
We show that an unknown quantum state in phase space can be teleported via three-mode entanglement generated by continuous variable quantum cloning machine (transformation). Further, proceeding with our teleportation protocol we are able to improve the fidelity of teleportation obtained by Loock et.al. [Phys.Rev.Lett. 84, 3482(2000)]. Also we study here the entanglement between the two output c...
متن کاملCriteria for Continuous-Variable Quantum Teleportation
We derive an experimentally testable criterion for the teleportation of quantum states of continuous variables. This criterion is especially relevant to the recent experiment of Furusawa et al. [Science 282, 706 (1998)] where an input-output fidelity of 0.58 ± 0.02 was achieved for optical coherent states. Our derivation demonstrates that fidelities greater than 1/2 could not have been achieved...
متن کاملDefending continuous variable teleportation: Why a laser is a clock, not a quantum channel
It has been argued [T. Rudolph and B.C. Sanders, Phys. Rev. Lett. 87, 077903 (2001)] that continuous-variable quantum teleportation at optical frequencies has not been achieved because the source used (a laser) was not ‘truly coherent’. Van Enk, and Fuchs [Phys. Rev. Lett, 88, 027902 (2002)], while arguing against Rudolph and Sanders, also accept that an ‘absolute phase’ is achievable, even if ...
متن کاملQuantum Teleportation with Continuous Variables: a survey
Very recently we have witnessed a new development of quantum information, the so-called continuous variable (CV) quantum information theory. Such a further development has been mainly due to the experimental and theoretical advantages offered by CV systems, i.e., quantum systems described by a set of observables, like position and momentum, which have a continuous spectrum of eigenvalues. Accor...
