Summary: We propose a theoretical strategy to manipulate an individual spin in a large array of spin qubits with random distribution of g factors. By utilizing single-qubit and SWAP gates with the help of a global microwave field and local exchange pulses, only the target qubit undergoes the desired operation while all other qubits return to their original states, even those with the same Larmor frequency as the target. Gate fidelities above 99% can be achieved for arrays containing tens of qubits.

Summary: The development of a pH-responsive electrode with switchable wettability is crucial for water electrolysis. A pH-responsive copper mesh/copolymer electrode was designed to alleviate the adhesion of hydrogen/oxygen bubbles during high-speed water electrolysis by adjusting the surface wettability. The kinetics of water oxidation and urea oxidation reactions on the electrode were examined, and the flexible water electrolysis performance of the pH-responsive electrode was investigated for the first time. The results demonstrated that the electrode accelerates certain reactions under better surface wettability while inhibiting them under poor surface wettability, providing insights for the development of water electrolyzers with different pH electrolytes and the design of water electrolysis electrodes.

Summary: This study proposes an electrochemical polymerization method to fabricate electrochemically switchable double-gate nanofluidic devices, which can in situ and reversibly switch among four different states of ion transport. By assuming the gate state as the input and the transmembrane ionic conductance as the output, the logic function of this nanofluidic device is systematically investigated. A biomimetic electrochemical ion pump is established by alternately applying two different specific logic combinations, realizing an active ion transport under a concentration gradient, which could inspire further studies to construct complex logical networks and explore bioinspired ion pump systems.

Summary: We have demonstrated high-fidelity on-chip entanglement between an incoming photon and a stationary quantum-dot hole spin qubit using self-assembled quantum dots integrated into nanostructures. The entanglement is induced by sequential scattering of the time-bin encoded photon interleaved with active spin control within a microsecond, two orders of magnitude faster than other solid-state platforms. The entanglement fidelity is immune to the spectral wandering of the emitter when conditioned on the detection of a reflected photon. These results represent a major step towards realizing a quantum node capable of interchanging information with flying photons and on-chip quantum logic for quantum networks and repeaters.

Summary: The uneven distribution of biochemical reactions in space and time leads to the diversity of biological systems. Liquid-liquid phase separation (LLPS) is a remarkable example of fine regulation of these reactions by the microenvironment. With a sensor based on gold nanoparticles, we demonstrate that interfacial factors in natural biological environments and sensors exhibit similar properties, repelling molecules outside the interface and adjusting DNA conformation within the interface to produce unique dynamics.

Summary: Monolayer-Protected Gold Clusters (AuMPCs) have attracted great interest as nanoscale capacitors in aqueous media for various nanobiotechnological applications. However, achieving subattofarad double-layer capacitance and single-electron charging has been challenging. In this study, we successfully synthesized Thioctic Acid Monolayer-Protected Au Clusters (TA-AuMPCs) that exhibited electrochemical single electron quantized capacitance charging in both organic and aqueous solutions. The functional carboxylic groups present in TA-AuMPCs provide a simple strategy for interfacing nanoparticles with biomolecules for biological electron transfer reactions.
