Ujjwal Gautam - A Brief Biography

Mr. Gautam is working on hybrid quantum technologies at the intersection of microwave-matter and optical-matter interactions. A key application of this hybrid interface is in microwave-optical transduction, which holds the potential to accelerate the scalability of superconducting quantum circuits by linking remote nodes via optical connections. Another promising direction is minimizing the coaxial cable complexity in large-scale qubit systems by replacing conventional microwave wiring with optical-to-microwave transducers. In such architectures, optical pulses can be transduced into microwave signals to drive qubit operations-eliminating the need for bulky microwave lines in and out of dilution refrigerators.

Mr. Gautam's research focuses on Yb:YSO, a rare-earth-ion-doped crystal with long spin and optical coherence times, enabling efficient interfacing with both microwave and optical fields. He is exploring the idea of quantum transduction integrated with quantum memories, leveraging Yb:YSO's unique properties. Utilising QCloud Lab's expertise in quantum memories, he aims to demonstrate a functional hybrid quantum device.

Beyond the lab, Mr. Gautam is deeply engaged in entrepreneurship and is an active member of the Hunter Hub for Entrepreneurial Thinking. He envisions a career at the superposition of quantum research and entrepreneurship, actively pursuing innovations with real-world impact.
