Welcome to the Quantum Defects and Photonics (QDP) Laboratory!
We are a research group working on quantum defects and quantum photonics in the department of Electrical and Computer Engineering at Rice University. Our lab explores defect-based spins in silicon with telecom optical interfaces as qubits for quantum information processing towards quantum networking and computing applications. We develop novel quantum optical and spin control techniques and protocols to manipulate the quantum states of the qubits and engineer interactions between them. On a system level, we aim to build hybrid integrated silicon quantum photonic chips consisting of spin-based quantum memories and other photonic circuit elements, as multiplexed quantum registers and repeaters, for realizing scalable hybrid quantum networks to connect different quantum systems.

[7/6/2024] Texas BBQ!
Ulises and Adam successfully defended their MS thesis on 6/27/2024 and 7/3/2024, respectively. Congratulations!
Junior students Qiyang Huang and Xiao Hu from University of Science and Technology of China (USTC) will join us over the summer research internships. Qiyang will work on the cQED modeling and Xiao will work on the spectroscopy.
Looking forward for a productive summer!
[10/30/2023] First Lab Paper!
Adam, Ulises and Yu-En posted the group's first paper on arXiv today: "Cavity-coupled telecom atomic source in silicon" describing the Purcell enhancement of a single T center in a silicon nanophotonic cavity. The work uses photoluminescence excitation spectroscopy to probe single T centers and analyzes cavity-QED of the coupled system. This is a major step towards utilizing single T centers in silicon for quantum information processing and quantum networking applications. Rice News Release.
