However, we need both noisy and noise-free data to train neural networks to mitigate errors in quantum computing results. Here, we propose a physics-motivated method to generate training data for quantum error mitigation via neural networks, which does not require classical simulation and target circuit simplification. In particular, we propose to use the echo evolution of a quantum system to collect noisy and noise-free data for training a neural network. Under this method, the initial state evolves forward and backward in time, returning to the initial state at the end of evolution. When run on a noisy quantum processor, the resulting state will be affected by the quantum noise accumulated during evolution. Having a vector of observable values of the initial (noise-free) state and the resulting (noisy) state allows us to compose training data for a neural network. We demonstrate that a feed-forward fully connected neural network trained on echo-evolution-generated data can correct results of forward-in-time evolution. Our findings can enhance the application of neural networks to error mitigation in quantum computing.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"23 12","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most existing QVPs are based on complex quantum technologies and <i>n</i>-particle entangled states, which impose substantial requirements on quantum equipment. What is more, the larger the parameter <i>n</i>, the more difficult the preparation and preservation of the <i>n</i>-particle entangled states. Furthermore, in most of the protocols, there is an issue of excessive reliance on a single trusted center, who masters the power of both verifying the vote and tracing the voter’s identity, which renders them vulnerable to the security risks resulting from potential abuse of single center’s power. To address these challenges, a semi-quantum voting protocol(SQVP) with decentralization of vote verification and traceability is proposed. In our protocol, the center Trent and the scrutineer Bob are quantum party, while all the voters are classical partners. The center Trent can only get the information on the vote's content without knowing the voter's identity, while the scrutineer Bob can only trace the identity of the voter without knowing the content of the vote. Therefore, our protocol can prevent from the abuse of single center’s power. The protocol can effectively withstand various eavesdropping and forgery attacks. To our knowledge, our protocol is the first SQVP utilizing the Bell state. Compared to similar QVPs, our protocol is more practical while ensuring security.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"23 12","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system is composed of three optical cavities and two nanomechanical resonators, with the middle optical cavity being filled with the two-level atomic ensemble. The optical cavity located in the middle has two interaction forces with the two outermost optical cavities. What is more, the system also includes various types of interaction relations, which are the couplings of the optical cavities with the mechanical resonators and the coupling of the optical cavity with the two-level atomic ensemble. In order to study the optical response of optomechanically induced transparency, we modulate the interaction intensity within the system to achieve different electromagnetic induced transparency phenomena. It has been found that under the influence of different parameters, the number and the width of transparency windows increase with an increase in the coupling of the optical cavities with atomic ensemble. In addition, changes in system parameters lead to shifts transparency points, specifically, the distance between the two outermost transparent points also expands when the couplings between the optical cavities and the mechanical resonators increases. We further examine the slow and fast light effects related to phase and group delay in the detection field. Our approach provides great flexibility for controlling electromagnetically induced transparency, presenting substantial potential applications in quantum information processing.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"23 12","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
