Blind quantum computing for everyone

(Phys.org)--For the first time, physicists have demonstrated that clients who possess only classical computers--and no quantum devices--can outsource computing tasks to quantum servers that perform blind quantum computing. "Blind" means the quantum servers do not have full information about the tasks they are computing, which ensures that the clients' computing tasks are kept secure. Until now, all blind quantum computing demonstrations have required that clients have their own quantum devices i...
