Structured Single-photon Metasource
Jun-Yong Yan, Fang-Yuan Li, Zhou Zhou +18
Structured quantum light is crucial for high-dimensional quantum information processing, yet its direct generation from quantum emitters remains challenging due to their intrinsic…
Single mode lasing and spectral narrowing in photonic crystal line-defect cavities via spatially selected Bloch modes
Shu-Ning Ding, Ling-Fang Wang, Xiao-Tian Cheng +10
The demand for high-efficiency and miniaturized on-chip light sources drives continuous innovation in photonic crystal (PhC) microcavity lasers. The presence of slow-light effects…
Enhancing Photon Indistinguishability of Spectrally Mismatched Single Photons by Cavity Floquet Engineering
J. W. Yu, X. Q. Zhou, Z. B. Ni +6
We theoretically propose a scheme to enhance the photon indistinguishability of spectrally mismatched single photons via Floquet-engineered optical frequency combs (OFCs) in cavity…
All-optical ultrafast arbitrary rotation of hole orbital qubits with direct phase control
Jun-Yong Yan, Liang Zhai, Hans-Georg Babin +10
Complete quantum control of a stationary quantum bit embedded in a quantum emitter is crucial for photonic quantum information technologies. Recently, the orbital degree of freedom…
Wavelength-tunable high-fidelity entangled photon sources enabled by dual Stark effects
Chen Chen, Jun-Yong Yan, Hans-Georg Babin +16
The construction of a large-scale quantum internet requires quantum repeaters containing multiple entangled photon sources with identical wavelengths. Semiconductor quantum dots ca…
