Optically trapped mixed-species single atom arrays with arbitrary geometry are an attractive and promising platform for various applications, because tunable quantum systems multiple components provide extra degrees of freedom experimental control. Here, we report the first demonstration two-dimensional 6×4 dual-species assembly ^{85}Rb (^{87}Rb) atoms a filling fraction 0.88 (0.89). This atomic synthesis is achieved via rearranging initially randomly distributed by sorting algorithm...
We demonstrate high fidelity single-qubit gate operation in a trapped single neutral atom. The atom is the recently invented magic-intensity optical dipole trap (MI-ODT) with more stable magnetic field. MI-ODT efficiently mitigates detrimental effects of light shifts thus sufficiently improves performance qubit-gates. gates are driven microwave, and characterized by using randomized benchmarking method. obtain an average error per Clifford $3.0(7)\times10^{-5}$ which much below threshold...
Ultracold single molecules have wide-ranging potential applications, such as ultracold chemistry, precision measurements, quantum simulation, and computation. However, given the difficulty of achieving full control a complex atom-molecule system, coherent formation remains challenge. Here, we report an alternative route to coherently bind two atoms into weakly bound molecule at megahertz levels by coupling atomic spins their two-body relative motion in strongly focused laser with inherent...

Rizhao green tea (RZT), a renowned tea, is cultivated in China's northernmost region. Its unique environment endows it with strong chestnut- and seaweed-like aroma. This study sought to explore the volatile profiles of RZT pinpoint its key odorants by employing stir bar sorptive extraction (SBSE) coupled gas chromatography-mass spectrometry (GC-MS), determining odor activity value (OAV), performing chromatography-olfactometry (GC-O). A total 112 volatiles were identified, major compounds...
It is common belief that the equilibrium contact angle, corresponding to minimum system energy state, lies between advancing and receding angles. Here, we derive angles considering micro contacting processes on ideal rough 2D surfaces. Equilibrium obtained via minimization can be smaller than angle reach 0 degrees, at which hysteresis diminishes super-hydrophilic surface. Gibbs free analyses, numerical simulations physical experiments all confirm these new findings.

This paper presents an energy-efficient clustering method using random update (EECRU) for wireless sensor networks. We divide the network into preliminary clusters depending on temporal and spatial correlation of data. These are then updated by applying a dynamic policy cluster head rotation scheme, where change data energy residue sensors taken consideration to achieve high efficiency balance. The larger rate in cluster, higher its frequency. A node that has frequency is more likely be...

Adult skeletal muscle regeneration is mainly driven by stem cells (MuSCs), which are highly heterogeneous. Although recent studies have started to characterize the heterogeneity of MuSCs, whether a subset with distinct exists within MuSCs remains unanswered. Here, we find that population marked Gli1 expression, required for regeneration. The Gli1+ MuSC displays advantages in proliferation and differentiation both vitro vivo. Depletion this leads delayed regeneration, while transplanted...

Hybrid homomorphic encryption (a.k.a., transciphering) can alleviate the ciphertext size expansion inherent to fully by integrating a specific symmetric scheme, which requires selected scheme that be efficiently evaluated homomorphically. While there has been recent surge in development of FHE-friendly ciphers, concerns have arisen regarding their security. A significant challenge for transciphering community remains efficient evaluation algorithms undergone extensive study and...
