hybrid integration methods for on chip quantum Photonics
arXiv: Applied Physics, 2019Co-Authors: Je Hyung Kim, Shahriar Aghaeimeibodi, Jacques Carolan, Dirk Englund, Edo WaksAbstract:The goal of integrated quantum Photonics is to combine components for the generation, manipulation, and detection of non-classical light in a phase stable and efficient platform. Solid-state quantum emitters have recently reached outstanding performance as single photon sources. In parallel, photonic integrated circuits have been advanced to the point that thousands of components can be controlled on a chip with high efficiency and phase stability. Consequently, researchers are now beginning to combine these leading quantum emitters and photonic integrated circuit platforms to realize the best properties of each technology. In this article, we review recent advances in integrated quantum Photonics based on such hybrid systems. Although hybrid integration solves many limitations of individual platforms, it also introduces new challenges that arise from interfacing different materials. We review various issues in solid-state quantum emitters and photonic integrated circuits, the hybrid integration techniques that bridge these two systems, and methods for chip-based manipulation of photons and emitters. Finally, we discuss the remaining challenges and future prospects of on-chip quantum Photonics with integrated quantum emitters.

integration of quantum dots with lithium niobate Photonics
Applied Physics Letters, 2018Co-Authors: Shahriar Aghaeimeibodi, Mustafa Atabey Buyukkaya, Aziz Karasahin, Richard P Leavitt, Christopher J. K. Richardson, Boris Desiatov, Marko Loncar, Edo WaksAbstract:The integration of quantum emitters with integrated Photonics enables complex quantum photonic circuits that are necessary for photonic implementation of quantum simulators, computers, and networks. Thin-film lithium niobate is an ideal material substrate for quantum Photonics because it can tightly confine light in small waveguides and has a strong electro-optic effect that can switch and modulate single photons at low power and high speed. However, lithium niobate lacks efficient single-photon emitters, which are essential for scalable quantum photonic circuits. We demonstrate deterministic coupling of single-photon emitters with a lithium niobate photonic chip. The emitters are composed of InAs quantum dots embedded in an InP nanobeam, which we transfer to a lithium niobate waveguide with nanoscale accuracy using a pick-and-place approach. An adiabatic taper transfers single photons emitted into the nanobeam to the lithium niobate waveguide with high efficiency. We verify the single photon nature of the emission using photon correlation measurements performed with an on-chip beamsplitter. Our results demonstrate an important step toward fast, reconfigurable quantum photonic circuits for quantum information processing.The integration of quantum emitters with integrated Photonics enables complex quantum photonic circuits that are necessary for photonic implementation of quantum simulators, computers, and networks.

large scale silicon quantum Photonics implementing arbitrary two qubit processing
arXiv: Quantum Physics, 2018Co-Authors: Xiaogang Qiang, X K Zhou, Jianwei Wang, Callum M Wilkes, T Loke, Sean Ogara, Laurent Kling, Graham D MarshallAbstract:Integrated optics is an engineering solution proposed for exquisite control of photonic quantum information. Here we use silicon Photonics and the linear combination of quantum operators scheme to realise a fully programmable two-qubit quantum processor. The device is fabricated with readily available CMOS based processing and comprises four nonlinear photon-sources, four filters, eighty-two beam splitters and fifty-eight individually addressable phase shifters. To demonstrate performance, we programmed the device to implement ninety-eight various two-qubit unitary operations (with average quantum process fidelity of 93.2$\pm$4.5%), a two-qubit quantum approximate optimization algorithm and efficient simulation of Szegedy directed quantum walks. This fosters further use of the linear combination architecture with silicon Photonics for future photonic quantum processors.

large scale silicon quantum Photonics implementing arbitrary two qubit processing
Nature Photonics, 2018Co-Authors: Xiaogang Qiang, X K Zhou, Jianwei Wang, Callum M Wilkes, T Loke, Sean Ogara, Laurent Kling, Graham D MarshallAbstract:Photonics is a promising platform for implementing universal quantum information processing. Its main challenges include precise control of massive circuits of linear optical components and effective implementation of entangling operations on photons. By using large-scale silicon photonic circuits to implement an extension of the linear combination of quantum operators scheme, we realize a fully programmable two-qubit quantum processor, enabling universal two-qubit quantum information processing in optics. The quantum processor is fabricated with mature CMOS-compatible processing and comprises more than 200 photonic components. We programmed the device to implement 98 different two-qubit unitary operations (with an average quantum process fidelity of 93.2 ± 4.5%), a two-qubit quantum approximate optimization algorithm, and efficient simulation of Szegedy directed quantum walks. This fosters further use of the linear-combination architecture with silicon Photonics for future photonic quantum processors.

microstructure and domain engineering of lithium niobate crystal films for integrated photonic applications
Light-Science & Applications, 2020Co-Authors: Dehui Sun, Yunwu Zhang, D G Wang, Wei Song, Xiaoyan Liu, Jinbo Pang, Deqiang Geng, Yuanhua Sang, Hong LiuAbstract:Recently, integrated Photonics has attracted considerable interest owing to its wide application in optical communication and quantum technologies. Among the numerous photonic materials, lithium niobate film on insulator (LNOI) has become a promising photonic platform owing to its electro-optic and nonlinear optical properties along with ultralow-loss and high-confinement nanophotonic lithium niobate waveguides fabricated by the complementary metal–oxide–semiconductor (CMOS)-compatible microstructure engineering of LNOI. Furthermore, ferroelectric domain engineering in combination with nanophotonic waveguides on LNOI is gradually accelerating the development of integrated nonlinear Photonics, which will play an important role in quantum technologies because of its ability to be integrated with the generation, processing, and auxiliary detection of the quantum states of light. Herein, we review the recent progress in CMOS-compatible microstructure engineering and domain engineering of LNOI for integrated lithium niobate Photonics involving photonic modulation and nonlinear Photonics. We believe that the great progress in integrated Photonics on LNOI will lead to a new generation of techniques. Thus, there remains an urgent need for efficient methods for the preparation of LNOI that are suitable for large-scale and low-cost manufacturing of integrated photonic devices and systems. A review of recent progress in the microstructure and domain engineering of lithium niobate film on insulator (LNOI) has concluded that it is a promising photonic material for developing integrated nonlinear photonic devices. The review, conducted by a team of researchers from China and led by Hong Liu from Shandong University, found that the high-performance electro-optic and nonlinear optical properties of LNOI makes it an ideal platform for integrated Photonics. Furthermore, they also discovered that the microstructures could be constructed on LNOI platforms for photonic circuits using current manufacturing techniques such as complementary metal–oxide–semiconductor technology. The researchers concluded that the large-scale and low-cost manufacturing of integrated photonic devices and systems by mature manufacturing processes could lead to the development of new applications in optical communication and quantum technologies.

Hybrid integrated quantum photonic circuits
Nature Photonics, 2020Co-Authors: Ali W Elshaari, Wolfram Pernice, Kartik Srinivasan, Oliver Benson, Valery ZwillerAbstract:The Review summarizes the progress of hybrid quantum Photonics integration in terms of its important design considerations and fabrication approaches, and highlights some successful realizations of key physical resources for building integrated quantum devices, such as quantum teleporters, quantum repeaters and quantum simulators. Recent developments in chip-based photonic quantum circuits have radically impacted quantum information processing. However, it is challenging for monolithic photonic platforms to meet the stringent demands of most quantum applications. Hybrid platforms combining different photonic technologies in a single functional unit have great potential to overcome the limitations of monolithic photonic circuits. Our Review summarizes the progress of hybrid quantum Photonics integration, discusses important design considerations, including optical connectivity and operation conditions, and highlights several successful realizations of key physical resources for building a quantum teleporter. We conclude by discussing the roadmap for realizing future advanced large-scale hybrid devices, beyond the solid-state platform, which hold great potential for quantum information applications.

hybrid quantum photonic integrated circuits
International Conference Laser Optics, 2018Co-Authors: Ali W Elshaari, Esmaeil I Zadeh, A Fognini, Dan Dalacu, P J Poole, Michael E Reimer, Valery Zwiller, Klaus D JonsAbstract:Quantum photonic integrated circuits require a scalable approach to integrate bright on-demand sources of entangled photon-pairs in complex on-chip quantum photonic circuits. Currently, the most promising sources are based on III/V semiconductor quantum dots. However, complex photonic circuitry is mainly achieved in silicon Photonics due to the tremendous technological challenges in circuit fabrication. We take the best of both worlds by developing a new hybrid on-chip nanofabrication approach, allowing to integrate III/V semiconductor nanowire quantum emitters into silicon-based Photonics.
