“…Silicon-on-insulator (SOI) is prevalent for its compatibility with complementary metal-oxide-semiconductor (CMOS) technology. Thanks to the solid foundation laid by silicon electronics, a large variety of integrated photonic devices have been developed, with wide applications in both classical and quantum signal processing. , The existing abundance of silicon photonic devices can be conveniently used to construct a photonic computing architecture. Meanwhile, due to the high refractive index contrast between silicon waveguide and the substrate, light can be tightly confined, thus enabling high-density integration, as demonstrated in Figure a .…”

In the context of a doomed end of the Moore's law, various new types of computing architectures have been emerging, aiming to meet the demands of intractable computation and artificial intelligence. Photonic computing is a competitive candidate, in light of the inherent properties of photons, including high propagation speed, strong robustness, and multiple degrees of freedom to encode information. Also, the progress of integrated photonics continues to provide novel possibilities, apart from boosting the scalability and stability of photonic computing architectures. Moreover, an introduction of quantum technology might open a new chapter for photonic computing, from the view of single photons. In this Perspective, we highlight the unique features and advances of integrated photonic platforms, whose roles in constructing a non-von Neumann computing architecture are also outlined. We show their potential in solving problems beyond the reach of traditional computers and in machine learning and further discuss the conceivable challenges and opportunities.

“…The systems often involve numerous independent building blocks, such as beam splitters (BSs), modulators and delay lines [1,2], which always need a large space and bear mechanical and thermal disturbances [3,4]. Compared to free-space optics and fiber optics, photonic integrated circuits (PICs) are promising platforms to overcome these difficulties due to their small footprint, scalability, programmability, and stability [5][6][7][8][9]. PICs provide opportunities to demonstrate large-scale quantum information processing that contains numerous optical components with millimeter scale, that is, quantum photonic integrated circuits (QPICs) [10,11].…”

The dense quantum entanglement distribution is the basis for practical quantum communication, quantum networks and distributed quantum computation. To make entanglement distribution processes stable enough for practical and large-scale applications, it is necessary to perform them with the integrated pattern. Here, we first integrate a dense wavelength-division demultiplexing system and unbalanced Mach-Zehnder interferometers on one large-scale photonic chip and demonstrate the multi-channel wavelength multiplexing entanglement distribution among distributed photonic chips. Specifically, we use one chip as a sender to produce high-performance and wideband quantum photon pairs, which are then sent to two receiver chips through 1-km standard optical fibers. The receiver chip includes a dense wavelength-division demultiplexing system and unbalanced Mach-Zehnder interferometers and realizes multi-wavelength-channel energy-time entanglement generation and analysis. High quantum interference visibilities prove the effectiveness of the multi-chip system. Our work paves the way for practical entanglement-based quantum key distribution and quantum networks.

“…Controlling of light-matter interaction has become more of an issue for the scientific and technological developments in the area of photonics [1][2][3]. In this regard, numerous optoelectronic and photonic devices in various research fields like quantum information, laser and sensor technologies [4][5][6] have been introduced and efforts have been made to couple quantum sources such as dye molecules, quantum dots (QDs) into these photonic devices to manipulate their spontaneous emission [7]. Photonic resonators are basically designed based on two parameters; the quality factor (Q-factor), which corresponds to the temporal confinement of the electromagnetic waves and the mode volume (V), which accounts for the spatial localization of the photons [8].…”

In this paper, a 1D photonic crystal waveguide and a plasmonic compound nano-system are utilized to design a hybrid photonic-plasmonic device for enhancement of light–matter interaction. Strongly localized light waves in a very small volume intensify the optical field, via surface plasmons due to presence of a gold nanoparticle, which interacts with the resonator’s cavity mode while the photonic crystal nanobeam ensures a high temporal confinement. The enhancement factor of light–matter interaction in the hybrid resonator is investigated through the single-atom cooperativity parameters based on numerically obtained results, which is calculated to be 14 as a result of the considerably reduced optical mode volume in the presence of the plasmonic nanoparticle. Additionally, the theoretical models and calculation procedures, presented in this paper, are demonstrated to be pioneering for the fabrication of efficient quantum devices based on hybrid photonic-plasmonic resonators.
