Quantum computing has undergone rapid development in recent years. Owingto limitations on scalability, personal quantum computers still seem slightlyunrealistic in the near future. The first practical quantum computer forordinary users is likely to be on the cloud similar to IBM’s Quantum Experience nowadays. In such asituation, it is of prime importance to keep the security of the client’sinformation. By extending the concept of homomorphic encryption in classicalcryptography to quantum cloud computing, we are able to open a feasible path tothe next stage of development of secure cloud quantum information technology. Formore details, please refer to the article “Homomorphic encryption experiments on IBM’s cloud quantum computing platform” by He-Liang Huang, et al., Front. Phys. 12(1), 120306 (2017).
