The core quantum resources of binary field multiplication are the qubit count and Toffoli depth of its quantum circuit, both of which are largely dependent on the Toffoli gate count. In this paper, we analyze the multiplicative complexity of binary field and present quantum circuits for (mathbb {F}_{2^8}) multiplication from the perspective of time and space. We find that the Toffoli gate count of quantum circuit corresponds to the bilinear complexity in (mathbb {F}_{2^n}) multiplication. The Toffoli gate count obtained by the algebraic curve method increases linearly with ({varvec{n}}), which is slower than the sub-quadratic complexity of Karatsuba algorithm and the iterated logarithm complexity of Chinese remainder theorem (CRT). To demonstrate the advantages of the algebraic curve method, we use elliptic curve bilinear algorithm in (mathbb {F}_{(2^2)^4}) and composite field arithmetic (CFA) to present two types quantum circuits for (mathbb {F}_{2^8}) multiplication, both of which have 24 Toffoli gates and are the lowest at present. The Toffoli depth of the time-efficient quantum circuit is only 1, and the product ({varvec{Dcdot W}}) of the depth and width of the circuit is 72, which is lower than before. The space-efficient quantum circuits require 24 qubits and maintain the Toffoli depth of 4, their ({varvec{Dcdot W}}) and Toffoli depth are reduced by at least 77.8(%) compared with the most advanced research.</div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949470","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}

While many researchers have used GANs to generate human faces and numeric images, others have applied them to learn and generate images from data distributions created by less distinct, chaotic systems. These chaotically generated images can serve as encryption keys for simple image encryption methods, potentially useful in military applications where data security is crucial, or in hospitals handling sensitive images like X-rays, CTs, MRIs, and physical photographs. Meanwhile, quantum GANs are still in their early research stages, primarily learning from distinct images like those in the MNIST or Fashion MNIST datasets. In this paper, we demonstrate that quantum machine learning models, specifically QGANs, can also learn from non-descript chaotic data distributions. We propose QryptGen (quantum crypt generator), which produces 28 (times ) 28 pixel grayscale image encryption keys. We show that encryption keys generated through quantum machine learning techniques can achieve a level of security comparable to those generated by classical deep learning techniques, thus confirming the potential of quantum machine learning to contribute broadly beyond just image encryption. Specifically, our study employs patch QGAN with a minimal number of qubits to maximize quantum advantages on NISQ devices, enhancing practicality.</div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944245","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}

Our results show that the self-Kerr effect of magnon (which depends on the intensity of the magnons) can significantly enhance multipartite entanglement, which turns out to be nonreciprocal when the magnetic field is tuned along different crystallographic axes. This is due to the frequency shift on the magnons (YIG sphere), which depends upon the magnetic field’s direction. Interestingly, the degree of nonreciprocity of bipartite entanglements depends upon a careful optimal choice of system parameters like normalized cavity detunings, bipartite nonlinear index (Delta E_{K}), self-Kerr coefficient, and effective magnomechanical coupling rate G. In addition to bipartite entanglement, we also present the idea of a bidirectional contrast ratio, which quantifies the nonreciprocity in tripartite entanglements. Our present theoretical proposal for nonreciprocity in multipartite entanglement may find applications in diverse engineering nonreciprocal devices. Furthermore, the current scheme might enhance the functionality of magnonic devices, and improve sensing capabilities.</div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944378","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}
