Title: Testing quantum systems
Duration: 01/2011 - 12/2013
Principal Investigator: Mario Ziman

Project Goals: Project is focused on problem in the field quantum "reverse engineering", i.e. on testing of properties of quantum devices aiming to their identification. The main goal of the project is to design efficient algorithms (if they exist) for testing of quantum properties assuming only incomplete information on input test states, on testing of the memory effects in quantum devices and on so-called unconditional identification of a (closed) set of quantum devices.
