Single Photon Source(单光子源)研究综述
Single Photon Source 单光子源 - The implementation of large scale integrated quantum photonic technologies requires on-chip reconfigurable waveguide circuits as well as single-photon sources and detectors. [1] We demonstrate hybrid quantum photonic circuits comprising Si3N4 waveguides featuring losses in the dB/m range, with directly integrated quantum dot based single-photon sources. [2] Color centers in diamond attract considerable attention as a room-temperature single-photon source. [3] Single solid-state quantum dots have significant potential as bright single-photon sources for scalable photonic quantum information technologies. [4] Nowadays, most of the on-chip plasmonic single-photon sources emit an unpolarized stream of single photons that demand a subsequent polarizer stage in a practical quantum cryptography system. [5] Electrically-driven single-photon sources (SPSs) are required for the scalable quantum technologies. [6] Our robust spatial and polarization control of emission provides an efficient way to demonstrate deterministic and scalable single-photon sources by integrating with nanocavities. [7] Semiconducting quantum dots (QDs) have potential applications in light-emitting diodes, single-photon sources and quantum computing due to shape-dependent (opto) electronic properties. [8] Hexagonal boron nitride (h-BN) has been recently found to host a variety of quantum point defects, which are promising candidates as single-photon sources for solid-state quantum nanophotonic applications. [9] This work provides a basis for the realization of applications such as heralded MIR single-photon sources, infrared imaging, and infrared spectroscopy based on quantum technologies in the MIR region. [10] The creation of single-photon sources on a chip with nanoscale apertures is a mid-term milestone on the road to chip-scale quantum computing. [11] Semiconductor quantum dots in cavities are promising single-photon sources. [12] Specifically, I will present data demonstrating arrays of single-photon sources, method for extremely economical nanotexturing as well as a modular molecular interface between biology and solid-state. [13] Here we report on the development and commissioning of a highly specialized 1010 nm fiber amplifier for such a novel parametric single-photon source. [14] The search for an ideal single-photon source has generated significant interest in discovering novel emitters in materials as well as developing new manipulation techniques to gain better control over the emitters’ properties. [15] Our single-photon source with only one input port is more compact and scalable compared to standard implementations. [16] This compact filter can be a basic building block for various applications requiring high extinction ratio filtering, such as single-photon source filtering of integrated photon chips. [17] Therefore, this type of cavities would allow for the realization of efficient single-photon sources. [18] A combination of advanced light engineering concepts enables a substantial improvement in photon extraction efficiency of micro-cavity-based single-photon sources in the telecom O-band at ∼1. [19] This includes indistinguishable single-photon sources, deterministic sources of entangled photonic states, photon-heralded entanglement generation between remote quantum systems, and deterministic optically-mediated entangling gates between local quantum systems. [20] Room temperature single-photon sources (SPSs) are critical for the emerging practical quantum applications such as on-chip photonic circuity for quantum communications systems and integrated quantum sensors. [21] We also highlight the prospects of perovskite quantum dots as single-photon sources, the design of new classes of colloidal quantum dots and superlattices for emerging applications and the role of hybrid device architectures in compensating for the limited carrier mobility in colloidal quantum dot solids while maintaining their tunable spectral response. [22] The results are in agreement with our theoretical analysis and highlight the potential of intrinsic optical resonances for developing nanodiamond-based lasers and single-photon sources. [23] Single-photon source in micro- or nanoscale is the basic building block of on-chip quantum information and scalable quantum network. [24] The new structure of the GeV color center has good prospects for use in sensors and single-photon sources. [25] We show the adoption of the imperfect entangled state generated from SPDC source is superior to that of the imperfect single-photon state from a practical heralded single-photon source. [26] We also discuss methods for the on-chip integration of such single-photon sources and related opportunities for the readout of solid-state spins. [27] In particular, they provide a control over the emission directionality, which is essential for single-photon sources and LED applications. [28] Our analysis shows that a heralded single-photon source can significantly improve the transmitted distance of UBQC and a modified coherent source can reduce the required transmitted number of pulses. [29] The proposed nanoantenna can be useful in the development of plasmonic sensors, display pixels, and single-photon sources. [30] Quantum optical memories are a key component in a variety of quantum information applications, from extending quantum communication channels to building high-efficiency single-photon sources to enabling protocols requiring multiple synchronized qubits. [31] A single-photon source is an essential tool for the emerging field of quantum technologies. [32] We present a novel semiconductor single-photon source based on tensile-strained (111)-oriented GaAs/InAlAs quantum dots (QDs) exhibiting ultrasmall exciton fine-structure splitting (FSS) of ≤ 8 µeV. [33] Deterministically integrated single-photon sources in nanoplasmonic circuits lead to densely packed scalable quantum logic circuits operating beyond the diffraction limit. [34] We report on a simple nanopost single-photon source geometry based on a quantum dot in a mesa placed on a metal mirror. [35] This work could pave a step towards a scalable array of QD single-photon sources and the application of QD photon-pair emission for entanglement experiments. [36] We apply an InGaAs quantum dot based single-photon source for the absolute detection efficiency calibration of a silicon single-photon avalanche diode operating in Geiger mode. [37] We present a numerical investigation of the performance of the micropillar cavity single-photon source featuring an elliptical cross section. [38] The high-purity single-photon source plays an important role in the field of quantum information. [39] Germanium vacancy (GeV) centers in diamonds constitute a promising platform for single-photon sources to be used in quantum information technologies. [40] Here, by using an on-demand single-photon source based on a semiconductor quantum dot embedded in a micropillar cavity, we demonstrate a heralded controlled-NOT (CNOT) operation between two single photons for the first time. [41] 2 µm corresponding to the spectral width of the single-photon source of 79. [42] However, for practical reasons, single-photon sources should be pumped electrically, which is required for integrability, scalability, and energy efficiency. [43] From all types of plasmonic and photonics nanostructures developed for room-temperature single-photon source applications the highest Purcell factor with increasing emitter radiative decay rate and enhancement in the total fluorescence intensity were obtained with metal plasmonic patch (gap) nanoantennas. [44] Unlike the other known methods for multichannel interferometers measurements, proposed technique is robust to the input and output phase fluctuations and does not require any single-photon sources and detectors. [45] Using a strain-reducing layer (SRL) these QDs can be employed for the manufacturing of single-photon sources (SPS) emitting in the telecom O-Band. [46] ABSTRACT As a non-classical light source, single-photon source plays an essential role in the foundation of quantum physics and has been attracting a lot of attention of researchers over the world. [47] Experimentally, a hyperentanglement of transverse-wave-vector and spectral modes can be obtained in a straightforward way with multimode parametric single-photon sources. [48] We explore both theoretically and experimentally how unwanted multiphoton components of single-photon sources affect the interference visibility, and find that the overlap between the single photons and the noise photons significantly impacts the interference. [49] We present the “photonic hourglass” structure as a candidate for a highly efficient single-photon source design.
