Scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons using an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet.

Professor Jelena Vučković has been awarded the Institution of Engineering and Technology (IET) A F Harvey Engineering Research Prize. She will develop an on-chip integrated pulsed laser, which will revolutionize photonic technology and the applications that require these lasers, such as medicine, optical communications, quantum computing and self-driving cars.

Just beyond the horizon of practicality, researchers are trying to develop a new generation of chips that would control photons as reliably as today’s chips control electrons. Jelena Vuckovic has already devoted some 20 years to this pursuit for a simple reason: Photonic chips could become the basis for light-based quantum computers that could, in theory, break codes and solve certain types of problems beyond the capabilities of any electronic computer.

In recent months the Stanford electrical engineer has created a prototype photonic chip made of diamond. Now, however, in experiments described in Nature Photonics, she and her team demonstrate how to make a light-based chip from a material nearly as hard as diamond but far less exotic — silicon carbide.

"These are early stage but promising results with a material that is already familiar to industry," Vuckovic said.

Congratulations to Q-FARM 2019 Fellowship Awardees

The inaugural recipients of the 2019 Q-FARM student fellowships are

  • Yudan Guo (Physics) is member of Prof. Benjamin Lev’s research group, LevLab. Yudan's research is centered on many-body cavity QED. 

  • Yihui Quek (Applied Physics) is in Prof. Weissman’s Compression group. Her research areas are quantum Shannon theory and near-term quantum algorithms.

The QFARM student fellowships are awarded to advanced graduate students working in quantum science and engineering. Fellowship criteria are excellence in their research, and demonstrated potential for building new links within the Stanford quantum community. Each of the awardees will receive two years of funding.
Please join us in congratulating PhD candidates Yudan Guo and Yihui Quek.

Integrated nanophotonics promises a generation of spiffy, miniaturized optical components that could drive new capabilities, in applications from communications to lidar to quantum technology. But getting there requires packing huge optical functionality into a very small footprint—and that has been a formidable challenge in design, fabrication and just plain time.

After decades of patient scientific groundwork, the notion of “quantum computing” has, in the past several years, seen a surge in new activity and interest—not only in the lab, but at commercial firms like Google, Microsoft and IBM, and even among the public at large. Spurring that new interest have been successful lab demonstrations of systems and simulations involving multiple quantum bits (qubits) in trapped-ion systems, superconducting circuits and other platforms.
