This scheme consists of two stages: quantum teleportation and assisted cloning. To fulfil the purpose, the first stage of this scheme requires bidirectional controlled teleportation via our constructed five-qudit maximally entangled state as quantum channel, where two distant communicators can simultaneously exchange their unknown single-qudit states with unit fidelity and unit probability under the permission of the supervisor.In the second stage,the state preparer disentangles any remaining entangled states by introducing two auxiliary particles, implementing a unitary transformation and two single-particle projective measurements. Subsequently, they transmit a specific number of classical bits to two distinct communicators in order to generate two precise replicas of different unknown states. Subsequently, the above scheme is extended with a certain probability and unit fidelity by replacing the above d-dimensional quantum channel with a five-qudit non-maximally entangled state. Finally, we further analyze the expansion issues of our scheme from the perspectives of positive operator-valued measurement (POVM for short), general quantum channel and the number of state preparers and controllers, and point out that the scheme is secure.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141572767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the dual-channel time-series prediction tasks as standard benchmark, the effects of feedback parameters (feedback strength, filter bandwidth, feedback detuning) and type on normalized mean square error (NMSE) were explored in detail. We found that: Selecting a smaller filter bandwidth can widen the range of values of feedback strength corresponding to smaller NMSE, which can effectively strengthen the robustness of parallel VCSEL-RC; When the feedback detuning varies from positive to negative value, the range of parameters space for feedback strength-filter bandwidth corresponding to lower NMSE tends to be narrowed; Compared with parallelly polarized FOF (PP-FOF), orthogonally polarized FOF (OP-POF) shows a stronger robustness enhancement; For smaller feedback strength, NMSE value is insensitive to the interior parameters of VCSEL. We also evaluated the processing rate of parallel VCSEL-RC with FOF. This study is valuable on enriching the understanding for nonlinear dynamics of FOF-based VCSEL-RC, and can provide a design guideline towards parallel, dual-channel RC with robust performance.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141549374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
