Quantum computing on encrypted data - Krister Shalm

With the rise of the internet we now rely on numerous remote servers and companies to process and store our personal information. The problem is that we must implicitly trust that these remote services, like Facebook and Gmail, will not abuse the information we have shared with them. The question arises about whether it is possible for a server to carry out computations on data that is encrypted. This would allow someone to use remote servers to process their sensitive data without needing to reveal any information. In this talk I will discuss a recent protocol and experiment that solves the quantum version of this problem. With only a few extra quantum resources it is possible for a powerful quantum server to process encrypted quantum data sent from a client with a weak quantum computer. This makes it possible to build secure distributed quantum networks while protecting privacy.
