Summary: In this study, a microchannel-based electrochemiluminescence (ECL) biosensor was used for the detection of adenosine triphosphate (ATP). The sensing performance of the biosensor relied on the change in charge density on the microchannel surface caused by a target recognition reaction. The system showed a linear relationship between ECL intensity and the logarithm of ATP concentration, with a detection limit of 0.32 fM.

Summary: The distributions of life molecules in live systems form complex dynamic reaction networks, and it is challenging to demonstrate their dynamic distributions in live systems. We proposed a dynamic analysis strategy using sequence-structure bispecific RNA with state-adjustable molecules to monitor the dynamic concentration and spatiotemporal localization of biomolecules in live cells, based on the insight of fluorescent RNA (FLRNA) interactions and their mechanism of fluorescence enhancement. A structure-switching aptamer (SSA), a novel FLRNA with sequence and structure bispecificity, was introduced to monitor the real-time concentration and spatiotemporal localization of biomolecules, providing a deeper understanding of the dynamic monitoring and visualization of biomolecules in live systems.

Summary: Continuous monitoring of driven-dissipative quantum-optical systems is crucial for achieving highly precise measurements beyond the classical limit. We design a novel continuous-measurement strategy and develop a universal method to efficiently retrieve the quantum Fisher information. We also establish an effective formula for evaluating the quantum Fisher information of the emission field of driven-dissipative open sensors.

Summary: We achieve a significant improvement in the precision of small-tilt measurement by combining a Sagnac interferometer, balanced homodyne detection, and weak-value amplification technique. Compared with split detection, balanced homodyne detection offers smaller minimum measurable tilt and higher signal-to-noise ratio. With our experimental setup, a precision of 3.8 nrad is obtained. The results demonstrate that the combination of weak-value amplification technique and balanced homodyne detection can complement each other's advantages and perform better in certain application scenarios, such as extremely weak output and wider measurement bandwidth. Furthermore, precision can be further enhanced through experimental parameter optimization.

Summary: This study investigates the amplification mechanism in weak measurement based on post-selection, revealing that amplification stems from the interference between the local oscillator and signal components. The amplification magnitude is proportional to the interference strength dominated by post-selection and coupling strength. The theory explains the amplification limit in the weak-value amplification strategy and the anomalous amplification in the almost balanced weak-values amplification strategy.

Summary: This study proposes a teleportation protocol for teleporting an unknown qubit through amplitude damping channels. By utilizing environment-assisted measurement and weak measurement, high fidelity and high success probability can be achieved during the teleportation process. For third-party assisted teleportation, the decoherence of shared entanglement can be completely suppressed by using environment-assisted measurement.

Summary: This study proposes a protocol for criticality-enhanced sensing by continuously observing the emitted radiation quanta. The study establishes a scaling theory for the global quantum Fisher information and derives universal scaling laws related to critical exponents. The findings suggest that the precision scaling of continuous detection of emitted quanta exceeds that of direct measurement, indicating the metrological value of this approach in dissipative criticality.

Summary: This paper focuses on the measurement of dynamic signals at points of interest (POIs) using a mobile agent. Existing work in mobile sensing has mainly focused on tracking known or unknown POIs, ignoring signal dynamics. Challenges arise in capturing and recovering the dynamics at each POI using intermittently measured data, resulting in temporal-spatial coupling. A compressed-sensing based approach is proposed to tackle this problem, addressing the trade-off between sensing cost and performance. Simulation studies show the effectiveness of the proposed approach in measuring temperature-dependent nanomechanical variations.

Summary: In this paper, an interferometric arrangement using weak value amplification technique is proposed to enhance the impact of a single photon on the quadratures of a movable mirror in an optical cavity. The photon interacts weakly with the mirror through radiation pressure and is postselected in the dark port of the interferometer. The real and imaginary parts of weak values of angular momentum type photonic operators lead to amplification of the mirror quadratures, which is more significant compared to the scenario without postselection.

Summary: We demonstrate the parametric coupling between two modes of a silicon nitride membrane by applying an oscillating voltage to a sharp metal tip near the membrane surface. The modes exchange energy periodically and faster than their free energy decay rate when the voltage oscillation frequency matches the mode frequency difference. This flexible method can be useful for rapid state control and transfer between modes, and is an important step towards parametric spin sensing experiments with membrane resonators.

In this study, we demonstrate the use of bosonic codes to simulate dynamical gauge fields by encoding matter and gauge fields in a network of resonators coupled via three-wave mixing. Our findings provide insights into preserving necessary gauge symmetries and promote the realization of high-energy models using bosonic codes.

Summary: This paper proposes using the purity as an indicator for the formation of strong correlations to observe impurity physics and verifies the feasibility of this approach by solving the open Kondo box model in the small box limit. The study characterizes the metal-to-insulator phase transition in the system and identifies the quenching of the conducting dot-lead Kondo singlet by the formation of an insulating intraimpurity singlet. Additionally, an experimentally feasible tomography protocol for the measurement of purity is proposed, which motivates the observation of impurity physics through the buildup of entanglement.

Summary: We analyze the generation and destruction of entanglement in a one-dimensional quantum spin chain under locally noisy and disordered Hamiltonian using the concept of a measurement-induced entanglement transition. By continuously measuring the system, we induce a transition from volume to area-law scaling of the steady-state entanglement entropy. The critical measurement strength is systematically reduced by static background disorder, but the dependence on the strength of nonstatic noise is nonmonotonic. According to the extracted finite-size scaling exponents, the universality class of the transition is independent of the noise and disorder strength.
