About the Sun Group

We are grateful for funding for our research from these agencies

Our group explores light-matter interactions at the fundamental quantum limit, where single atoms can strongly interact with single photons. We realize this capability by design and fabrication of nanophotonic structures that confine photons at an extremely small volume, which are then coupled to solid-state artificial atoms such as quantum dots and atomic defect centers. In addition to the interest of understanding fundamental physics through the generation of exotic light-matter interactions, we aim to apply the quantum light-matter interface for quantum information applications, including long-distance quantum networking, optical quantum computing, and distributed quantum computing.

Research Areas

  • Qubits exist in nature (e.g. single atoms or photons), but we can also create them by our own. Our group studies optically active solid-state qubits such as quantum dots and color centers. Similar as single atoms, these qubits possess…

  • We aim to develop key enabling technologies to facilitate the transmission of quantum information among physically separated quantum nodes. We focus on their applications in both quantum communication and quantum computing. For quantum…

  • Optical photons are ideal carriers of quantum information. But they were not considered to be suitable for quantum computing due to the lack of mechanisms for photon-photon interactions. The KLM protocol proposed in 2000 firstly reveals…

July 19, 2021: JILA Fellow Shuo Sun is awarded the Keck Foundation Grant for developing Quantum Technology

Two physicists at the University of Colorado Boulder and Colorado School of Mines have received a $1 million grant from the W.M. Keck Foundation to develop a first-of-its-kind quantum simulator that could be used to develop novel materials and, in the future, lead to the development of a high-performance quantum computer.
