Adopting quantum communication to modern networking requires transmitting quantum information through fiber-based infrastructure. We report the first demonstration of superdense coding over optical fiber links, taking advantage of a complete Bell-state measurement enabled by timepolarization hyperentanglement, linear optics, and common single-photon detectors. We demonstrate the highest single-qubit channel capacity to date utilizing linear optics, 1.665 ± 0.018, and we provide a full experimental implementation of a hybrid, quantum-classical communication protocol for image transfer.PACS numbers: 42.50. Ar,03.67.Bg,42.79.Sz Superdense coding enables one qubit to carry two bits of information between a sender Bob and receiver Alice when they share an entanglement resource, perhaps distributed at "off-peak" times [1]. Bob can choose to use this quantum ability at a time of optimal advantage, after the time of distribution, when he and Alice have access to quantum memory [2]. A significant challenge in realizing superdense coding is the need to perform a complete Bell-state measurement (BSM) on the photon pair, which is not possible using only linear optics and a single degree of shared entanglement [3,4]. While nonlinear optics [5] or utilization of ancillary photons and linear optics [6] enable a complete BSM, these methods are challenged by inefficiency and impracticality. However, a complete BSM with linear optics can be performed by using entanglement in additional degrees of freedom, so-called hyperentanglement [7,8]. Complete BSM implementations have been demonstrated previously using states hyperentangled in orbital angular momentum and polarization degrees of freedom [9] as well as with states hyperentangled in momentum and polarization [10]. However, these states are not compatible with transmission through fiber-based networks, which form the backbone of modern telecommunication systems. Previously, Schuck et al. have shown that timepolarization hyperentanglement can be used for complete and deterministic BSM [11], but required number resolving detectors to identify the states completely. Yet this encoding is attractive in that it permits efficient transmission through optical fiber and that some photon pair sources generate time entanglement for "free".In this article, we report results from an experimental demonstration of superdense coding over optical fiber links using a complete BSM based on time-polarization hyperentanglement. Our novel implementation requires only linear optics and common single-photon detectors. The resulting combination of a hyperentangled photon pair source and novel discrimination device yields an observed channel capacity of 1.665±0.018, the highest reported to date for a single-qubit and linear optics. We demonstrate the feasibility of this setup by transmitting a 3.4 kB image that is recovered with 87% fidelity.

“…SDN offers deep programmability of the network at all layers and even extends the network state into applications for enabling better pathing decisions. The OpenFlow protocol plays a key role in enabling SDN architectures through its simple, flexible and adaptable programming interface [4] At present, the mainstream SDN architecture is mostly devised according to the three-tier model, that is, the application layer, the control layer, and the forwarding layer , which are illustrated in Fig. 1.…”

Abstract.With the development of the Internet, information security has attracted great attention in today's society, and quantum cryptography communication network based on quantum key distribution (QKD) is a very important part of this field, since the quantum key distribution combined with one-time-pad encryption scheme can guarantee the unconditional security of the information. The secret key generated by quantum key distribution protocols is a very valuable resource, so making full use of key resources is particularly important. Software definition network (SDN) is a new type of network architecture, and it separates the control plane and the data plane of network devices through OpenFlow technology, thus it realizes the flexible control of the network resources. In this paper, a quantum cryptography communication network model based on SDN is proposed to realize the flexible control of quantum key resources in the whole cryptography communication network. Moreover, we propose a routing algorithm which takes into account both the hops and the end-to-end availible keys, so that the secret key generated by QKD can be used effectively. We also simulate this quantum cryptography communication network, and the result shows that based on SDN and the proposed routing algorithm the performance of this network is improved since the effective use of the quantum key resources.
