Research Overview

The field of quantum optics has led to the development of radically new ways to compute, communicate, and measure with quantum states. The Quantum Photonics Group is developing quantum technologies in scalable semiconductor systems, building on the dramatic achievements of semiconductor technology in past decades. Present goals include quantum simulators using scalable silicon photonic circuits and high-performance quantum memories based on electron spins in diamond color centers, high-speed quantum key distribution, and spin-off applications in opto-electronic devices for classical information processing. We are also pursuing new applications in precision measurements, including the development of electron spin-based timing devices and biosensors.

The Quantum Photonics Group is led by Dirk Englund, Jamieson Career Development Professor in Electrical Engineering and Computer Science at the Massachusetts Institute of Technology.
