Oblak, e. al | | Hybrid entanglement for optical quantum networksA global optical quantum communication network will have to operate with different encodings of quantum information (QI) depending on the medium in which the photons are carried. Polarization qubits in the visible spectrum are well suited for free-space transmission due to the absence of birefringence in the air, whereas time-bin qubits at telecom wavelengths are more suited for optical fiber transmission due to their resistance to polarization mode dispersion.
We present a scheme to generate hybrid photonic entanglement defined as entanglement between different encodings of QI using light. In this specific case we consider a time-bin photon at 1550 nm entangled with a polarization photon at 805 nm and we report on our progress towards creating such a source using parametric down-conversion in bulk crystals. We also show how to teleport a polarization qubit to a time-bin qubit using this type of entanglement. Finally, we discuss how this allows QI to be distributed over optical quantum networks interfacing free-space and optical fiber links hence increasing the versatility of such networks.

Tittel | | Towards Hybrid Quantum Key DistributionWe present a scheme for quantum key distribution based on hybrid entanglement. The idea is to couple a free-space link with an optical fibre link by generating polarization qubits in the visible spectrum entangled with time-bin qubits in the telecom window. We discuss two ways to generate this type of entanglement: Using parametric downconversion in a periodically-poled crystal or using four-wave mixing in optical fibres. We also discuss how hybrid entanglement is an interesting way to extend the range of quantum key distribution. University of Calgary, The University of Calgary | Presentation | 2007-06-18 | F.

Tittel | | Hybrid photonic entanglement using a PPLN crystalWe propose a scheme to generate hybrid photonic entanglement, defined as entanglement between photonic qubits with different encodings, using quasi phase-matched parametric downconversion in a periodically-poled lithium niobate (PPLN) crystal. The hybrid entanglement is obtained by first generating two time-bin entangled qubits at 810 and 1550 nm. Then, using standard fibre telecom components, the 810~nm qubit is deterministically converted to a polarization qubit which can be transmitted in free-space. We report on our progress towards building and characterizing such a source and discuss its utility in creating hybrid quantum networks.
