Quantum Physics for Nanotechnology and Information Processing

Professor Privman's main contributions in this field have been in developing and evaluating approaches to utilize semiconductor heterostructures and quantum wells, based on the silicon-chip device technology, for quantum information processing (quantum computing). (See Figure 1.) He has also worked in modeling electron transport of relevance to single-quantum measurement and control.

The new developing subjects of quantum computation and information, quantum cryptography, spintronics, and novel uses of semiconductor and laser technology in nanosize applications, fit within the national nanotechnology initiative. Professor Privman has received funding from the US Army Research Office and National Science Foundation. He also received a research program start-up award, jointly with CAMP Professors Ahmadi and Cheng, from the Semiconductor Research Corporation.
