Travis Nicholson Group

My research experimentally and theoretically explores quantum information, quantum optics, atomic physics, and quantum metrology. My experiments are based on ultracold atoms, which I use to study storing, transmitting, processing, and reading out quantum information. I also use exotic ultracold matter to explore novel atomic physics. My theoretical work focuses on using quantum optics to design technology that has a quantum advantage over classical systems. I also theoretically investigate quantum metrology, with a focus on improving global timekeeping and advancing quantum measurement.

Travis Nicholson is a Principal Investigator at the Centre for Quantum Technologies and an Assistant Professor of Physics at NUS. He performed his PhD research at JILA in the United States. His PhD thesis demonstrated the world's most accurate atomic clock, which neither gains nor loses a second in 15 billion years. After this he was a postdoctoral fellow at MIT, studying nonlinear quantum optics with Rydberg atoms. Travis joined the CQT in 2017.
