This trio (with others in their field) have pushed our understanding of Quantum Physics and established it as a part of Physics defying local realism. That is, the kind of physics that deals with 100% determined points in space and time.

While establishing this they also laid grounds for quantum information theory, which is the basis for quantum computing. This is now slowly turning into technology. The first out for potential commercial use is quantum encryption, that immediately reveals attempts to read the information sent (it prevents eavesdropping).
