Summary: This study reports the first demonstration of two-dimensional dual-species atom assembly, achieved by rearranging initially randomly distributed atoms using a sorting algorithm and optical trapping technique. The resulting atom arrays have user-defined geometries and specific species ratios, making them highly attractive for applications in high-fidelity quantum logic, many-body quantum simulation, and single molecule array formation.

Summary: The reversible reconfiguration of tetrahedra nanostructures from monomer structures into dimer or trimer structures is triggered by K+-ion-stabilized G-quadruplexes or T-A center dot T triplexes. This signal-triggered dimerization/trimerization is used for developing multiplexed miRNA-sensing platforms and intracellular sensing and imaging of miRNAs.

Summary: In this study, a novel ratiometric ECL sensing platform was developed based on ECL-resonance energy transfer (ECL-RET), enabling quantitative analysis of miRNA-133a with a limit of detection of 0.41 pM. The platform can also be easily extended to detect metal ions or aptamer substrates, and a series of sensitive logic gates based on ECL-RET ratiometry responded to as low as 100 pM of Hg2+ or Ag+.

Summary: For high-fidelity entangling gates based on transverse modes for mixed-species ion chains with large mass ratio, the laser power required is at least an order of magnitude higher than that for gates based on axial modes. Additionally, even with moderate mass differences, the transverse modes are much harder to cool than the axial modes.

Summary: By transferring QD films onto a Si substrate covered by Ag nanoparticles, an ultralong lifetime exciton emission in InAs/GaAs single quantum dots has been achieved. The long lifetime is attributed to the existence of a dark state in the wetting layer, which is induced by the destructive interference between the exciton emission field and the induced dipole field of the Ag nanoparticles. The classical dipole oscillator model is used for quantitative calculation and simulation of the spontaneous radiation decay rate of the excitons in the wetting layer.

Summary: This Letter presents theoretical and experimental investigations on the emission properties of quadrupolar excitons (QXs) in a WSe2/MoSe2/WSe2 heterotrilayer device. The optical brightness or darkness of QXs is determined by horizontal mirror symmetry, valley and spin selection rules. The emission intensity and energy of QXs can be adjusted by applying an out-of-plane electric field, due to changes in hole distribution and the Stark effect. The results provide experimental evidence for the existence of QXs in heterotrilayers and uncover their novel properties.

Summary: This study investigates the diffusion of excimers within a supramolecular assembly of BPEA chromophores on nanoporous membranes, demonstrating the possibility of delivering excitation energy to distant sites. Despite typically serving as low energy trap sites, the BPEA excimers are shown to be mobile, with higher diffusivity than other reported excimers and approaching that of singlet excitons in efficient organic photovoltaic systems.

Summary: This study proposes a simple and novel strategy to improve the sensitivity of FRET aptasensors by using DNA tetrahedron and gold nanorods. The method exhibits linear detection sensitivity in the concentration range of 0.01-10 ng/mL, with a limit of detection of 0.005 ng/mL. The developed biosensor demonstrates efficient specificity, good accuracy and stability, and performs well in real samples.

Summary: Internal states of polar molecules can be controlled by microwave-frequency electric dipole transitions, which also affect the motion of the particles if a spatial gradient of the microwave electric field is applied. This capability enables the construction of phonon-mediated quantum gates between trapped polar molecular ion qubits without the need for laser illumination or cooling near the motional ground state, providing a high-speed quantum processing toolbox for dipoles in thermal motion that combines precision microwave control and long coherence times.

Summary: An enzyme-free and label-free fluorescent DNA aptasensor was constructed with computer assistance for the sensitive detection of acetamiprid. This strategy enables detection at concentrations as low as 54.3 pM by triggering interchain reactions and self-assembly. Computer-assisted analysis and simulation tests prove the feasibility of this strategy and basic molecular logic gates were also constructed. This research provides a potential pathway for molecular logic computing.
