ENTANGLEMENT QUANTUM RANDOM NUMBER GENERATOR WITH PUBLIC RANDOMNESS CERTIFICATION

摘要

As the quantum random number generators are gaining in popularity, especially with regard to possibility of construction of a scalable quantum computer, a new invention is proposed in this area based upon topological properties of quantum entanglement. The proposed Entanglement Quantum Random Number Generator (Entanglement QRNG) uses a certain multi-qubits entanglement of quantum states to produce randomness with public certification. The invention describes both the protocol and its generic implementing device, involving the specific 3-qubits quantum entanglement of generalized Bell state type (topologically inequivalent to different types of entanglements and easily generalized to multiple-qubits as shown in the invention description), characterized also in the topological terms, that enables private quantum random number generation with a publicly accessible proof of randomness, thus allowing an external party to freely and publicly verify the randomness of the generated sequence without disclosing of its secrecy or distorting it in any way (this feature of QRNG is proposed for the first time and has an important role for applications in both quantum and classical cryptography).
