"Quantum Networking with Semiconductor Quantum Dots"

The field of semiconductor cavity quantum electrodynamics has seen rapid progress in the past several years. One of the main reasons for this is the development of high quality factors optical micro-cavities with mode volumes that are less than a cubic wavelength of light. These cavities allow previously unattainable interaction strengths between optical fields and atomic systems.

Of the many ways to develop optical microresonators, photonic crystals are currently one of the most promising approaches. Photonic crystal structures allow us to guide and confine light on the size scale of an optical wavelength, and to integrate a large number of nanophotonic components on a single semiconductor chip. When coupled to “artificial atoms”, such as semiconductor quantum dots, they provide a practical method for developing large scale quantum devices on a semiconductor chip.

In this talk I will discuss our work on the integration of photonic crystals with Indium Arsenide quantum dots for engineering of quantum devices. I will describe practical methods for entangling quantum dots to form large scale quantum devices, with the potential for scalable quantum computation in a semiconductor system.


Edo Waks received his Ph.D. in Electrical Engineering from Stanford University in the area of quantum optics and quantum information. After graduating, he became a postdoctoral fellow at Stanford University, working on nanophotonic implementations of quantum information processing. He joined the faculty at the Department of Electrical and Computer Engineering at the University of Maryland, College Park, in the Fall of 2006.

Waks is a National Science Foundation (NSF) Fellow and was a member of Tau Beta Pi, the engineering honor society, at Stanford. He won the Department of Central Intelligence Postdoctoral Fellowship Award sponsored by the Army Research and Development Activity, which funded his postdoctoral research. He received a National Science Foundation Graduate Fellowship (1996-1999), and the William Huggins Award for Outstanding Achievement in Computer and Electrical Engineering, from Johns Hopkins University (1995).
