Abstract

The invention provides an integrated optical chip system for distributed security quantum information processing. The integrated optical chip system comprises a server integrated optical quantum chip and a user integrated optical quantum chip. The server integrated optical quantum chip comprises a configurable entanglement multi-photon source which is used for generating a plurality of photons and outputting the photons to a server linear optical network and a user linear optical network according to wavelengths; the server linear optical network which is used for preparing an initial state for the photons output by a wavelength division multiplexer, carrying out unitary transformation and linear combination, carrying out combination and carrying out projection measurement on the combined photons; and a user integrated optical quantum chip which transmits linear term coefficients through quantum teleportation so as to linearly combine each term of unitary transformation in the server integrated optical quantum chip. The server cannot know the specific computing task of the user, and the user is informed of the result through a classic channel after computing is completed. By using the technical scheme of the invention, the computing privacy of the user can be protected.

Description

technical field [0001] The invention relates to the technical field of quantum computing, in particular to an integrated optical chip system oriented to distributed secure quantum information processing. Background technique [0002] Quantum computing is a new computing model that follows the laws of quantum mechanics and performs calculations by regulating quantum information units, namely qubits. Quantum computing is a new type of computing model based on quantum mechanics. It uses quantum superposition, interference and entanglement properties to perform calculations. It has natural parallelism and large information storage capabilities, so it has a huge potential that classical computing cannot match. Many application fields, such as large number prime factorization, database search, chemical molecular simulation, etc., have great application potential. [0003] Linear optical systems are one of the main physical approaches to quantum computing. Its main advantages inc...
