Encapsulated CsPbBr3 quantum dots with asymmetric chiral magneto-optoelectronic responses

Quantum emitters having non-trivial spin polarizations are highly demanded for chiral quantum devices and quantum photonic technologies. Here we investigate the magneto photoluminescence spectroscopy of perovskite quantum dots encapsulated in silica and report an observation of c...

A Configurable and Highly Efficient NTT/INTT/PWM Unit for CRYSTALS-Kyber and CRYSTALS-Dilithium

CRYSTALS-Kyber and CRYSTALS-Dilithium are representative lattice-based post-quantum cryptographic schemes, where number theoretic transform (NTT), inverse NTT (INTT), and point-wise multiplication (PWM) dominate polynomial arithmetic. Existing hardware accelerators are typically...

Thermally Modulated Microfluidic Fabrication of Phase-Tunable Cs4PbBr6/CsPbBr3 Hybrid Perovskite Nanocrystals for White Light-Emitting Diodes

All inorganic CsPbBr3 perovskite nanocrystals (NCs) exhibit outstanding luminescence for optoelectronics, yet poor environmental stability severely restricts their practical deployment. As a stable derivative phase, Cs4PbBr6 can effectively improve structural stability. Neverthel...

A Microseismic Energy Field Distribution Prediction Method Guided by Geological Structure Priors

Existing microseismic prediction methods commonly incorporate domain prior knowledge as ordinary input features, which makes it difficult to fully exploit its structural constraints and physical implications. To address this limitation, this study proposes a geological-structure-...

PCA–GPR-Assisted Sequential Bayesian Inversion of Slope Mechanical Parameters from Multi-Stage Deep Horizontal Displacement Monitoring

Reliable mechanical parameters are needed to predict deformation during staged slope excavation, yet deep inclinometer profiles are high-dimensional and repeated numerical inversion is costly. This study integrates principal component analysis, Gaussian process regression (GPR),...

An engineered metal-to-insulator transition in a two-dimensional network of degenerate phosphorus quantum dots in silicon

Phosphorus quantum dots (QDs) in silicon are a prominent candidate for semiconductor quantum computing based on donor spins. In this work, we report the formation of degenerate phosphorus QDs with a radius of 3 nm confined in a two-dimensional plane in silicon. A multilayer of Si...

65 TOPS optoelectronic multi-core computing unlocking multi-feature fusion enhancement

The rapid progress of artificial intelligence demands scalable, energy-efficient hardware with massive parallelism and high throughput. Although optical computing offers a promising post-Moore solution, current implementations face speed limitations and multi-core integration cha...
