Feasible Quantum Technology for Secure Classical Computing
Abstract
Quantum Computers allow for dramatic computational speed-ups and for a hithertounknown level of data security due to the concept of blind quantum computing. Whereasthe development of a full-fledged quantum computer is still a significant challenge,quantum communications technology is already well-established and outperforms theirclassical counterparts by exploiting rather modest resources.We aim to combine the advantages of powerful classical computers and small, wellcontrollable quantum systems for achieving quantum-enhanced software and dataprotection via the implementation of probabilistic one-time programs. In particular we willencode classical gates onto flying quantum bits, which are transmitted to a receiver thatcan evaluate the classical computer program only once. This enables a new era ofquantum-enhanced software security, whereby computations can be delegated to remotecomputers in such a way that the program can be reliably run on a given input, while at thesame time a malicious user is prevented from obtaining a complete description of theprogram.We will use and optimize feasible photonic quantum technology for building a prototypesystem that combines conventional classical gates with quantum gates whose input rely onthe quantum encoding in single photons. Our insights and achievements go hand in handwith the experimental investigation of various encryption schemes for quantum computersas well as the development of new quantum-enhanced encryption schemes for classicalcomputers.
