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…
Optically Active Single Hole Spin in ZnSe
Amirehsan Alizadehherfati, Yuxi Jiang, Kelsey J. Mirrielees +7
Semiconductor hole spins offer a pathway to extended coherence times by decoupling from nuclear magnetic noise, while their spin-orbit coupling enables fast all-electrical control.…
Hardware-Efficient Universal Linear Transformations for Optical Modes in the Synthetic Time Dimension
Jasvith Raj Basani, Chaohan Cui, Jack Postlewaite +2
Recent progress in photonic information processing has spurred strong demand in scalable and reconfigurable photonic circuitry. Conventional spatially-meshed multi-port interferome…
Electrical Control of Optically Active Single Spin Qubits in ZnSe
Amirehsan Alizadehherfati, Yuxi Jiang, Nils von den Driesch +6
Electrons bound to shallow donors in ZnSe quantum wells are promising candidates for optically addressable spin qubits and single-photon sources. However, their optical coherence a…
Generation of Coherent Quantum Light from a Single Impurity-Bound Exciton
Yuxi Jiang, Christine Falter, Robert M. Pettit +5
Impurity-bound excitons in II-VI direct-bandgap semiconductors are promising optically active solid-state spin qubits that combine exceptional optical quantum efficiency with an ul…
