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 solid-state spins in silicon with telecom optical interfaces as qubits for quantum information processing towards quantum network and computing applications. We develop novel 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 quantum networks.


We thank Rice and the following funding agencies for supporting our research!

[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.
