Key research interests:

Our goal is to perform research and development on the commercial exploitation of quantum information processing (QIP). While our primary long-term goal is the implementaton of a large-scale quantum computer, all technologies related to QIP, including quantum communication and quantum cryptography, are of interest to us.

Within the next few years, we plan to construct prototypes of quantum information devices and to build a portfolio of useful intellectual property. We intend to set up R&D laboratories (in house and/or through collaborations).
