Surface passivation for narrowing optical linewidth of silicon T centers in nanophotonic devices
Fariba Islam, Chang-Min Lee, Kyu-Young Kim +3
Silicon T centers are promising spin-photon interfaces in solid-state platforms for telecom-compatible, scalable quantum information technologies. A major challenge for T centers i…
Bright Telecom Spin-Photon Interface in Silicon Photonics
Carolina Crosta, Amirehsan Alizadehherfati, Purbita Purkayastha +5
Silicon is an attractive host for scalable quantum photonics, but the absence of bright telecom-band emitters with optically addressable spin states has limited its use for spin-ph…
Long-lived quantum correlation by cavity-mediated subradiance
Kyu-Young Kim, Jin Hee Lee, Woong Bae Jeon +5
Cooperative effects such as super(sub)radiance in quantum systems arise from the interplay among quantum emitters. While bright superradiant states have been extensively studied an…
Efficient, indistinguishable telecom C-band photons using a tapered nanobeam
Mohammad Habibur Rahaman, Samuel Harper, Chang-Min Lee +7
Telecom C-band single photons exhibit the lowest attenuation in optical fibers, enabling long-haul quantum-secured communication. However, efficient coupling with optical fibers is…
