Size effects on vitrification have been observed in other glassy materials such as metallic glasses and polymers, but their impact on hybrid glasses has yet to be explored. In this study, we examine the size-dependent vitrification behavior of hybrid glasses using fast scanning calorimetry across a broad range of heating and cooling rates. Our results are similar to that observed in polymer and metallic glasses, the glass transition temperature (<i>T</i>_<i>g</i>) is not significantly influenced by sample size at the micro-meter scale at cooling rates larger than or equal to 30 K/s. Furthermore, the vitrification enthalpy displays a clear dependence on sample size, with smaller samples exhibiting a larger overshoot enthalpy, which is attributed to a reduction of fictive temperature values (<i>T</i>_<i>f</i>) with size. These features originate from the network structure and flexibility of coordination bonding. Our findings suggest that the vitrification enthalpy is more fundamental than the temperature in size effects and that the low enthalpy state of smaller hybrid glass samples has implications for their functional properties.</p></div>","PeriodicalId":774,"journal":{"name":"Science China Physics, Mechanics & Astronomy","volume":"68 6","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Currently, various quantum simulators provide powerful tools for researchers, but simulating quantum evolution with these simulators often incurs high time costs.

To address this issue, our research aims to utilize Large Language Models (LLMs) to simulate quantum circuits. This paper details the process of constructing 1-qubit and 2-qubit quantum simulator models, extending to multiple qubits, and ultimately implementing a 3-qubit example. Our study demonstrates that LLMs can effectively learn and predict the evolution patterns among quantum bits, with minimal error compared to the theoretical output states. Even when dealing with quantum circuits comprising an exponential number of quantum gates, LLMs remain computationally efficient. Overall, our results highlight the potential of LLMs to predict the outputs of complex quantum dynamics, achieving speeds far surpassing those required to run the same process on a quantum computer.

The underlying reason for this phenomenon is that adjusting the phase and coupling strength via the phase shifter and IWG bring the system close to an exceptional point (EP), where field localization dynamically enhances the optomechanical nonlinearity, leading to the generation of chaotic motion. In addition, due to the sensitivity of chaos to phase in the vicinity of the EP, we propose a theoretical scheme to measure the optical phase perturbations using chaos.

Device-independent (DI) and measurement-device-independent (MDI) QSDC protocols theoretically enhance the practical security of QSDC. However, DI QSDC requires extremely high global detection efficiency and has a limited secure communication distance. Both DI and MDI QSDC protocols depend on high-quality entanglement. Current entanglement sources, which generate entangled photon pairs with low efficiency, significantly reduce their practical communication capabilities. In this paper, we propose a single-photon-based receiver-device-independent (RDI) QSDC protocol. This protocol relies solely on the practical single-photon source, which is nearly on-demand with current technology, and treats all receiving devices on both ends of the communication as “black boxes”. The security of the message is ensured only through the observed statistics. We also develop a numerical method to simulate the protocol’s performance under practical noisy communication conditions. The RDI QSDC protocol provides the same security level as MDI QSDC. Compared to DI and MDI QSDC, RDI QSDC has several advantages. First, it uses single-photon sources and single-photon measurements, which allow it to achieve practical communication efficiency approximately 3415 times greater than that of DI QSDC, while being easier to implement. The entire protocol is feasible with current technology. Second, it offers higher robustness to photon loss and better noise tolerance than DI QSDC, enabling a secure communication distance approximately 26 times greater than that of DI QSDC. Based on these advantages, the RDI QSDC protocol presents a promising approach for achieving highly secure and efficient QSDC in the near future.</p></div>","PeriodicalId":774,"journal":{"name":"Science China Physics, Mechanics & Astronomy","volume":"68 5","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

EP will detect X-ray tidal disruption events and outbursts from active galactic nuclei, possibly at an early phase of the flares for some. EP will monitor the variability and outbursts of X-rays from white dwarfs, neutron stars and black holes in our and neighbouring galaxies at flux levels fainter than those detectable by the current instruments, and is expected to discover new objects.
