Alp Sipahigil

Alp Sipahigil is the Ping & Amy Chao Family Assistant Professor of Electrical Engineering and Computer Sciences at the University of California, Berkeley. He holds joint appointments as a Faculty Scientist at Lawrence Berkeley National Laboratory's Materials Sciences Division and a supporting appointment in UC Berkeley Physics. His research focuses on solid-state quantum devices for quantum computing, communication, and sensing, particularly exploring superconducting circuits, color centers, integrated photonics, and phononics.

Education:

• PhD in Physics, Harvard University (2017)
• B.S. in Physics and Electrical Engineering, Bogazici University (2010)

Research interests include advancing quantum technologies through device engineering, with emphasis on coherence control in superconducting qubits, spin-photon interfaces in silicon, and phononic bandgap materials. His work bridges quantum materials, nanotechnology, and hybrid systems. Recent efforts target scalable silicon-based quantum photonics and defect engineering in quantum systems.

Key achievements include demonstrating indistinguishable photons in silicon photonics (Nature Communications, 2024) and developing phononic bandgap structures to mitigate qubit decoherence (Nature Physics, 2025). He leads the Berkeley Quantum Devices Group, fostering interdisciplinary collaboration between EECS, physics, and materials science.

Awards: Rose Hills Innovator Program (2024). Research affiliations include the Berkeley Emerging Technologies Research (BETR), Berkeley Sensor & Actuator Center (BSAC), and NSF Challenge Institute for Quantum Computation (CIQC).
