Research Abstract |
We developed new approaches based on techniques from quantum computing to efficiently handle computational problems with an algebraic structure. Among our main results, we constructed new algorithms for distinguishing, in the framework of property testing, classes of groups, and new quantum algorithms for computing efficiently the product of two Boolean matrices. As applications of these novel approaches, we succeeded in proving the hardness of decoding problems arising in quantum communication, and in constructing new protocols for several tasks such as privacy-preserving communication.
