However, there needs to be more emphasis on asymmetric ones, such as Einstein–Podolsky–Rosen (EPR) steering. In this study, we delve into EPR steering between two frequency-modulated qubits coupled to a zero-temperature reservoir individually, in both weak and strong coupling regimes. We consider a scenario where each qubit is locally identically coupled to its environment. The results demonstrate that the decay of EPR steering between the two qubits can be delayed remarkably by controlling frequency modulation parameters, regardless of whether the system exhibits Markovian or non-Markovian behavior. Moreover, we observe that a precise balance between modulation strength <span>(delta )</span> and frequency <span>(varOmega )</span>, determining the zeros of the Bessel function <span>(J_{0}(delta /varOmega ))</span>, can significantly enhance EPR steering in the strong coupling regime. Furthermore, we investigate the asymmetric nature of EPR steering by examining a scenario where one of the qubits remains unmodulated. We thoroughly analyze the impact of modulation parameters on the occurrence of EPR steering sudden death. The findings highlight that asymmetry properties, such as one-way and two-way steering, can be effectively manipulated by adjusting the frequency modulation parameters, even when the initial two-qubit state is symmetrical. These results suggest that it is feasible to safeguard EPR steering and control its asymmetry properties without requiring additional quantum resources.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 10","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210883","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}

On the way towards an answer to this problem, we map a small critical infrastructure network on a quantum network composed of dipole–dipole-coupled nodes. The latter are each equipped with up to three discrete (quantum) states, two of which support the connectivity of the network, while the third state, reachable through nondeterministic spontaneous processes, represents a ‘broken’ node. A finite ‘repair’ time is needed to restore the node. To study the dynamics of such networks on a quantum computer, we derive unitary dilations of Kraus operators governing the evolution of our open quantum network, and generate corresponding quantum circuits using the <span>qiskit</span> interface. We then study the population dynamics of several cases of increasing complexity on the quantum hardware. We discuss how scaling of errors is related to the depth of the quantum circuits. Ultimately, we show that open quantum systems can be used for modelling critical infrastructure, but quantum computers with much lower error rates than currently available are required for a quantitative resilience analysis.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 10","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11128-025-04947-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gaussian quantum steering characterizes steerability, while logarithmic negativity quantifies entanglement. Our analysis reveals that the entanglement between the two Rms is strongly influenced by temperature, magnon mode detuning, the orbital angular momentum (OAM) of the LG modes, magnon-cavity coupling strength, and the mass of the RMs. The magnon-photon coupling emerges as a key parameter for controlling and manipulating the RMs entanglement. A weak mass of the RMs serves to be an advantageous factor that improves the amount of entanglement and makes it strong in the face of thermal effects. GGD increases with rising RMs mass. Within experimentally accessible parameters, we achieve two-way steering. The GGD shows a robustness against thermal effects compared to entanglement and steering.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 10","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210384","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}
