A prototype photonic integrated circuit.

Quantum Information and Integrated Nanosystems

In the area of quantum information science, we are developing superconducting and trapped-ion quantum bits and are working to scale up these bits to a size large enough to achieve quantum computing. We're also studying how to harness quantum mechanics to improve sensing, and so far, have produced a diamond-based magnetic-field sensor 1,000 times more energy efficient than previous magnetometers. Our group continues to pioneer semiconductor fabrication techniques, classical superconducting circuits, and photonic integrated circuits for applications in energy-starved sensors, optical communications and laser radar transceivers, and more. Recently, our focus has been on developing superconducting single-flux-quantum integrated circuits to address future high-performance computing needs. To this end, we have developed a novel CMOS fabrication process that is on track to enable the most advanced superconducting circuits ever constructed.
