He has also intered at National Renewable Energy Laboratory...
Color centers in silicon are emerging as promising candidates for photonic quantum processors. Among these color centers, the T center’s long spin coherence and telecom-band optical transitions make it an attractive target for quantum repeater and memory applications. Due to the T center’s long optical lifetime, cavity enhancement is an important prerequisite to any practical implementation of quantum protocols. In this work, we demonstrate a silicon photonics platform enabling a high yield of strongly enhanced T centers from distinct cavities through a single bus waveguide. We use a...
Transduction of signals between electrical, mechanical, and optical domains is central to modern computing, sensing, and communication systems. Emerging quantum computing, sensing, and communication technologies also require the development of transducers capable of converting quantum-level signals such as single photons and phonons with high efficiency and low loss. Traditional piezoelectric materials such as aluminum nitride and lithium niobate are widely used in classical piezoelectric and electro-optic transducers. However, for quantum applications, these thin films have large defect...
Kerry Yu is a Ph.D. candidate in Electrical Engineering and Computer Sciences (EECS) at UC Berkeley, advised by Prof. Alp Sipahigil. He earned his M.Sc. in Electrical and Computer Engineering from UCLA and High Honors B.Sc. in EECS from UC Berkeley. His current research focuses on the intersection between microwave and phononic engineering to mitigate the decoherence of superconducting qubits. Kerry is also a recipient of the NSF Graduate Research Fellowship.
Enrique Garcia is a new EECS PhD student at the University of California Berkeley. He is beginning work with Alp Sipahigil in the Quantum Devices Group as of 2025. He graduated from the University of Washington with his B.S. in Electrical Engineering in 2024. He has previously worked with Maxwell Parsons in the Quantum Technologies, Training and Testbed lab, primarily working on development of an NV center-based quantum register.
Lukasz Komza is a Physics PhD student at the University of California, Berkeley. He started working with Alp Sipahigil in the Quantum Devices Group in 2021 on the characterization and integration of silicon qubits in photonics. Prior to starting his PhD, Lukasz interned at Bell Labs in Murray Hill, NJ, working with Michael Eggleston on optical coherence tomography. He studied quantum light sources in 2D materials with Stefan Strauf during his undergraduate education, where he received the Alfred M. Mayer prize.
