Abstract

This paper demonstrates homomorphic-encrypted quantum computing using single-photon states and integrated optics. The client encrypts input data in the photons' polarization, while the server performs computations using the path degree of freedom. Experiments show successful unitary transformations of individual qubits and multi-qubit quantum walk computations, highlighting the potential for secure, non-interactive delegated quantum computing.
