Quantum Optics - Nanophotonics - Metrology - Photonic Networks

Quantum Silicon Photonics for unconditionally secure communication and other quantum technologies	Quantum-Enhanced Sensing for real-time imaging of neural activity in the brain; solid-state atomic clocks	Classical and quantum information processing devices and systems	Graphene Opto-Electronics
Modern silicon photonics for high-performance quantum information processing, such as QKD protocols running at 10 bits per photon.	Ultrasensitive measurements/quantum metrology to detect weak fields & forces in biology, chemistry, and physics; atomic clock analogs using electron spin states in diamond.	Guiding light at the wavelength-scale for new optoelectronic devices with ultra-low power consumption for next-generation computing and communication systems.	Graphene - silicon hybrid opto-electronic devices. Silicon photonic integrated circuits are combined with graphene for high-speed, low-power optical modulators, photodetectors, and nonlinear optics.

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.
