摘要
A fully homomorphic encryption system enables computation on encrypted data without the necessity for prior decryption. This facilitates the seamless establishment of a secure quantum channel, bridging the server and client components, and thereby providing the client with secure access to the server's substantial computational capacity for executing quantum operations. However, traditional homomorphic encryption systems lack scalability, programmability, and stability. In this Letter, we experimentally demonstrate a proof-of-concept implementation of a homomorphic encryption scheme on a compact quantum chip, verifying the feasibility of using photonic chips for quantum homomorphic encryption. Our work not only provides a solution for circuit expansion, addressing the longstanding challenge of scalability while significantly reducing the size of quantum network infrastructure, but also lays the groundwork for the development of highly sophisticated quantum fully homomorphic encryption systems.Received 3 September 2023Accepted 19 March 2024DOI:https://doi.org/10.1103/PhysRevLett.132.200801© 2024 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasOptical quantum information processingPhotonicsQuantum communicationQuantum cryptographyQuantum information processingQuantum networksQuantum opticsQuantum protocolsQuantum Information, Science & TechnologyAtomic, Molecular & Optical
