Blind quantum computing : from theory to implementation

In this talk, we will review twenty years of research in blind quantum computing

While most developers of quantum computers are developing cloud access to their devices, the question of privacy is becoming of paramount importance. Blind quantum computing directly answers this question. It is a way to encrypt a quantum circuit before sending it to a remote server that can run the computation without learning anything about the inputs, outputs or even the circuit itself. It can be considered as considered as a quantum equivalent of fully homomorphic computing.In this talk, we will review twenty years of research in blind quantum computing from the first theoretical proposals to most recent lab implementations. We will then discuss the engineering issues that remain to be solved in order to deploy this technology at a large scale.
