Applications of blind quantum computation - hiding a Grover search algorithm — •Alexander Sauer, Alexander von Consbruch, and Matthias Zimmermann — German Aerospace Center (DLR), Institute of Quantum Techologies, Wilhelm-Runge-Straße 10, Ulm, 89081, Germany

With quantum-capable devices becoming readily available and the ongoing development of quantum computers, quantum networks are within grasp. Apart from the enhanced computational power of quantum computers, these networks also provide new opportunities in security and secrecy. One new method that becomes available is blind quantum computing, in which a powerful quantum computer acts as a server and performs computations for a distant client without getting knowledge about details of the computation [1]. We investigate applications of blind quantum computing and the introduced overhead on communication between the involved parties and complexity on the quantum server. In particular, we present a protocol for a hidden Grover search algorithm utilizing additional qubits on a quantum server which are securely initialized by the client.
