Scalable quantum photonic systems
WHEN: 24 November, 2023
Recent breakthroughs in photonics design, along with new nanofabrication approaches and heterogeneous integration play crucial roles in building photonics for applications including optical interconnects and quantum technologies.
The implementation of scalable quantum systems is the most dramatic example of this effort, as it requires new photonic materials and device functionalities, together with stringent device performances. Towards this goal, the platforms based on color centers in diamond and silicon carbide have been considered promising candidates, because of their optically interfaced spin qubits, high speed and high-fidelity quantum gates, and high-quality photonics. While these platforms have usually been studied in the context of quantum networking, recent demonstration of coherent interactions of multiple qubits inside a single silicon carbide resonator has established this system as a promising candidate for quantum simulation and possibly even quantum computing.
However, truly scalable systems require integration of all passive and active photonic devices on the same chip, including sources. Following the same advances in design, fabrication, and heterogenous integration, even Titanium: sapphire laser, the workhorse of optics laboratories, can be miniaturized into sub-cubic centimetre volume together with its pump, and without any loss of performance.
Jelena Vuckovic is the Jensen Huang Professor in Global Leadership, a Professor of Electrical Engineering and by courtesy of Applied Physics at Stanford, where she leads the Nanoscale and Quantum Photonics Lab. She joined the Stanford Electrical Engineering Faculty in 2003, upon receiving her PhD degree from the California Institute of Technology (Caltech) in 2002. At Stanford, she has also served as the Fortinet Founders Chair of the Electrical Engineering Department, and was the inaugural director of QFARM, the Stanford-SLAC Quantum Initiative. She is affiliated with Ginzton Lab, PULSE Institute, SIMES Institute, Stanford Photonics Research Center (SPRC), SystemX Alliance, Bio-X, and Wu-Tsai Neurosciences Institute at Stanford.
Prof Vuckovic is recipient of the 2023 Geoffrey Frew Fellowship from the Australian Academy of Sciences, as well as many other notable accolades including Distinguished Scholarship of the Max Planck Institute for Quantum Optics in Munich, Marko V. Jaric Award for outstanding achievements in physics, Humboldt Prize and the Office of Naval Research Young Investigator Award. She was the Mildred Dresselhaus Lecturer at MIT, and the James Gordon Memorial Speaker at Optica. She is a Fellow of APS, OPTICA, IEEE and a member of the National Academy of Sciences.
