Summary: We present protocols for remote implementation of general operators between two nodes, utilizing simultaneous entanglement in two independent degrees of freedom. The protocols are fulfilled near deterministically in two steps, using cross-Kerr interaction and X-quadrature measurements in the first step and available optical elements and single-photon detectors in the second step. Our protocols are beneficial to long-distance quantum communication and quantum metrology.

Summary: This paper presents a multiple time delays FitzHugh-Nagumo (FHN) neuron system with chemical and electrical coupling. Both the coupled FHN neuron systems without and with time delays are investigated. The equilibria of the FHN neuron system without time delay are studied with variations in the strength of chemical and electrical coupling. The stability analysis of the coupled FHN neuron system with delays shows a stability switching through Hopf bifurcation.

Summary: The magnetic coupling between the orbital angular momentum L of a photoexcited cyclic pi-conjugated system and the total angular momentum J of a localized 4f electronic system in [Dy(TPP)(cyclen)]Cl has been identified using magnetic circular dichroism (MCD). The experimental results show antiparallel J-L interaction, and theoretical models provided quantitative agreement with the data. The relationship between the two orbital angular momenta L(pi) and L(f) from the delocalized pi system and the localized 4f system, respectively, was revealed through ab initio calculations.

Summary: This research proposes a quantum dialogue protocol based on single photons in both polarization and spatial-mode degrees of freedom (PSDF), which only requires two single unitary operations for implementation. Compared to other protocols, this protocol achieves a higher information-theoretical efficiency of up to 66.67%. The analysis shows that the proposed protocol is safe without information leakage, and it does not require auxiliary photons, making it easily implementable with current technology. Therefore, it is not only feasible in practice but also simple and efficient.

Summary: The development of the Koch curve fractal geometry provides valuable ideas for the structural design of sensors. Conventional eddy current sensors have limitations in concentrating electromagnetic energy and detection sensitivity. This article proposes a novel eddy current sensor based on the Koch curve fractal geometry, which can change the distribution of electromagnetic fields in space. The results of simulation and defect detection experiments demonstrate that the proposed sensor can effectively concentrate electromagnetic fields and improve detection performance.

Summary: In this study, biomimetic electromagnetic wave absorption materials (EAMs) were fabricated by analyzing covert information identifications and focusing on the design of metastructures and microstructures. Control and recognition of the electromagnetic waves' phase, amplitude, and angular momentum were achieved by manipulating the rotation angle of the meta atoms. The designed multilayer metamaterials realized effective absorption within the 4.5-18 GHz regime under 2.8 mm thickness, providing evidence for a new way for integrated EAMs and metamaterials.

Summary: The burst of Mars exploration in the past two decades has greatly enhanced our understanding of the Martian atmosphere. Observational records have shown Earth-like cycling of dust and water through the Mars system, as well as hints of dynamical coupling between the lower, middle, and upper atmosphere. These processes have been studied using advanced numerical models and recent observations, revealing similarities and differences with Earth's atmospheric coupling processes.

Summary: To overcome the limitations of traditional methods, the researchers utilize the structural degrees of freedom at the inter-meta-atom level to create new functionalities for metasurfaces and meta-devices. By fully exploiting these degrees of freedom, they successfully design a novel double-key-secured encryption system with increased image storage capacity approaching the theoretical limit. This generic design approach can be applied to other nanophotonic systems, expanding the functionalities of metasurfaces.

Summary: This paper proposes a design scheme of double-sandwich magnetic coupling structure with a low cross-coupling coefficient, which integrates the resonant inductors into the power transmitter and receiver, and it is designed taking the magnetic leakage and loss as constraints. A 500W prototype is built, and the comparison of experimental efficiencies between the double-sandwich and the separate magnetic coupling structures is performed. Finally, the effectiveness of the integrated design scheme is validated.

Summary: This study focuses on the singular value decomposition of the spin correlation matrix from the ground state of the one-dimensional antiferromagnetic quantum Heisenberg model. By determining the scaling relation for the singular values as a function of domain size, it was found that the singular values are closely linked to the square of weights of the bases in the ground-state wavefunction, allowing for a precise estimation of the appropriate bases and corresponding weights of the ground-state wavefunction.

Summary: This study numerically investigates the generation of phonon quantum entanglement in photoirradiated remote electron-phonon systems. It is found that the generation of phonon entanglement is a two-step process that can be controlled by designing the temporal properties of incident optical pulses. The dynamics of phonon entanglement can be observed through time-resolved spectroscopy on the scattered light.

Summary: The electronic properties of excitonic insulators and spin-state transitions in perovskite cobalt oxides have been examined. By using the density matrix renormalization group method and an effective model for the one-dimensional two-orbital Hubbard model, the spatial spin structures depending on crystal and magnetic fields were investigated. Excitonic insulating and spin-state ordering phases were found in the intermediate region between low and high-spin phases. In the excitonic insulating phase, spatially fluctuating spin-triplet excitons and incommensurate spin correlations were observed. The spin gap and entanglement spectra suggest the presence of Haldane-like edge states. In the spin-state ordering phase, different spin-state structures were stabilized depending on the crystal field splitting.
