Yvonne Gao Group

The Quantum Circuits Research and Engineering Workgroup (QCREW) is a multi-disciplinary team striving to tackle some of the most pertinent challenges in quantum computing hardware developments. Our main research focus is to develop modular quantum devices with superconducting quantum circuits and pave the way for a large-scale quantum computer. This requires the development of robust processes to simulate, optimise, and fabricate bespoke quantum circuits for our experiments, with a strong emphasis on producing circuits with precise and reproducible parameters.

Additionally, we are also keen to use our quantum devices study other interesting physical effects, from quantum interference to multipartite interactions, at milli-kelvin temperatures. Our systems can also provide versatile test-beds for developing new quantum models and algorithms.

We are seeking motivated PhD students and Research Fellows to join our team. For more information, please visit our group website https://quantumcrew.org or reach out to Yvonne directly.

Yvonne earned her doctorate from Yale University from the group of Robert J. Schoelkopf. Her work focused on developing multimode operations between multiphoton quantum states encoded in superconducting cavities.

In 2019, Yvonne was named one of the Innovators Under 35 (Asia Pacific) by MIT Tech Review for her work in developing crucial building blocks for quantum computers. She was also awarded the National Research Foundation Fellowship (Class 2020) to start a new research initiative in Singapore focusing on building modular quantum devices with superconducting circuits.
