Abstract

We demonstrate experimentally that it is possible to prepare and detect photon pairs created by spontaneous parametric down-conversion which exhibit simultaneous position-momentum and polarization correlations that are adequate to implement a four-dimensional key distribution protocol.

Simultaneous observation of correlations in position-momentum and polarization variables

Marcelo Pereira de Almeida, Stephen Patrick Walborn, P. H. Souto Ribeiro

We demonstrate experimentally that it is possible to prepare and detect photon pairs created by spontaneous parametric downconversion which exhibit simultaneous position-momentum and polarization correlations. We discuss the use of these correlations in several four-dimensional key distribution protocols.

Experimental investigation of quantum key distribution with position and momentum of photon pairs

Marcelo Pereira de Almeida, Stephen Patrick Walborn, P. H. Souto Ribeiro

We investigate the utility of Einstein-Podolsky-Rosen correlations of the position and momentum of photon pairs from parametric down-conversion in the implementation of a secure quantum key distribution protocol. We show that security is guaranteed by the entanglement between down-converted pairs, and can be checked by either direct comparison of Alice and Bob's measurement results or evaluation of an inequality of the sort proposed by Mancini et al. [Phys. Rev. Lett. 88, 120401 (2002)].

Generation of polarization entanglement utilizing spatially correlated photon pairs from spontaneous parametric down-conversion

T. Yamaguchi, Ryōsuke Shimizu, Yasuyoshi Mitsumori +2 more

Polarization entanglement of photons provides a superior environment to demonstrate quantum info-communication protocols. Thus far, several methods using parametric down-conversion process have been realized to generate polarization-entangled photon pairs. In this report, we propose a novel method to generate polarization entanglement from spatially correlated photon pairs and demonstrate its experimental verification.

Experimental conversion of position correlation into polarization entanglement

Chithrabhanu Perumangatt, Alexander Lohrmann, Alexander Ling

This paper presents a method to convert position correlation of photon pairs into polarization entanglement. This is achieved by individually manipulating the polarization state of photons generated in different parts of a nonlinear medium and coherently superposing them. This concept is experimentally demonstrated using photon pairs produced by spontaneous parametric down-conversion. The method is used to implement a compact source producing an observed photon-pair rate of $120\phantom{\rule{0.16em}{0ex}}000\phantom{\rule{4.pt}{0ex}}{\text{s}}^{\ensuremath{-}1}/\text{mW}$ with an entanglement fidelity of $0.991\ifmmode\pm\else\textpm\fi{}0.013$. This method can be extended to any photon-pair generation process with initial position correlation.

Entangled-photon quantum cryptography

Paul G. Kwiat, Andrew G. White, Charles G. Peterson +1 more

Summary form only given. Quantum cryptography uses single photons to allow secure distribution of secret key material to sender and receiver, without the possibility of an undetected eavesdropper. In the protocol suggested by Ekert, each photon of a quantum-mechanically entangled pair is sent to the sender and receiver, who randomly measure the polarization in various bases. If the bases are the same, then sender and receiver will have completely correlated measurement results, which become the shared secret key. Other combinations of measurements are used to test Bell's inequalities, which limit the possible correlations achievable with any local realistic theory. The presence of an intermediate eavesdropper can be readily detected by an inability to violate Bell's inequality. Using the polarization-entangled photon pairs from a novel spontaneous parametric down-conversion source, we have experimentally implemented. Ekert's proposal.

Generation and characterization of a source of wavelength division multiplexing quantum key distribution

Atsushi Yabushita, Takayoshi Kobayashi

Using spontaneous parametric down-conversion, photon pairs entangled in frequency and polarization were generated. After frequency resolving the photon pairs, the polarization correlations were measured on several polarization basis, and it was confirmed that the frequency resolved photon pairs were entangled in polarization, indicating the photon pairs can be used as a source of wavelength division multiplexing quantum key distribution.
