High‐Dimensional Remote State Preparation with Metasurface‐Based Hyper‐Entangled Photon Source

Minghao Ning, Nachuan Li, Haozong Zhong +12 more

Abstract A high‐dimensional quantum network with multiple degrees of freedom provides enhanced channel capacity and noise resilience, making it highly significant for quantum communication. However, achieving quantum networks with high‐dimensional hyper‐entanglements using traditional optical systems presents substantial challenges. In this study, the generation of a compact high‐dimensional hyper‐entangled photon source utilizing a metasurface is demonstrated. Furthermore, a scalable protocol for the remote preparation of high‐dimensional single‐photon states, ranging from 3 to 8 dimensions based on this entangled light source is theoretically proposed and experimentally validated. The average fidelities of the remotely prepared states all exceed 0.9. This metasurface‐based approach to quantum communication protocols presents a promising avenue for the development of large‐scale quantum networks and distributed quantum computing systems.

Spectrally Multimode Photon Pair Source

Xiong, YanJuan

The development of the quantum computer challenges the security of classical communication. This is due to the security of classical encryption being based on the computational complexity of an algorithm, for example, the difficulty of factoring a number into its prime product. Quantum communication uses quantum mechanics to manipulate quantum states and exchange information between two locations. Quantum communication has proven to be unconditionally secure. However, the fact that the maximum transmission distance is largely limited by attenuation in the distribution link remains one of the biggest challenges for practical quantum communication. Quantum repeaters can greatly extend this communication transmission distance. To realize quantum repeaters, one requires quantum memories, entanglement swapping operations, and photon pair-sources. In addition, quantum repeaters greatly benefit - in terms of the achievable entanglement distribution rate - if they can incorporate some form of multiplexing. Multiplexing is possible in any of the available photonic modes, which for transmission in single-mode fibers amounts to polarization, spectral, and temporal modes. The polarization degree of freedom is undesirable because it only has two orthogonal modes. The choice of the spectral or temporal modes for multiplexing then depends on what is most compatible with other components in the setup, particularly the quantum memory, which is the most demanding component. Based on prior demonstrations in the lab of spectral multiplexing in rare-earth ion doped crystals, the purpose of my project has been to build a spectrally multi-mode photon pair-source. Our implementation of the spectrally multi-mode photon pair sources relies on a nonlinear optics process that involves the interaction of strong light and a non-linear crystal. To achieve the spectral selection of specific modes, the non-linear crystal is combined with a suitable cavity.

Phillip S. Blakey, Zacharie M. Léger, Trevor J. Stirling +2 more

The non-local cancellation if dispersion is used to reduce accidental counts caused by multi-photon noise by 7.27 times in an SPDC Source. This makrs the first demonstration of a fully waveguided system enhancing a single photon detectors resolution to effectively reject uncorreltaed multi-photon noise from SPDC sources. This advancement has helps address a critical challenge in achieving higher pair rate SPDC sources without the associated degradation in state quality with applications for quantum sensing and communications.
