Refined Kerr-effect-based high-dimensional quantum gate.

High-dimensional quantum gates not only extend the existing quantum computing framework but also serve as a vital component in a range of quantum technologies. In the study, a 4 × 4-dimensional controlled-NOT (CNOT) gate is presented based on the assistance of a weak cross-Kerr medium, utilizing only two degrees of freedom (DoFs) with two photons. Specifically, the control qudits are encoded in the photonic polarization DoF, while the target qudits are encoded in the path DoF of the two photons.

Error-heralded high-dimensional quantum gate with robust fidelity.

Quantum computing in high-dimensional spaces holds promise for a plethora of applications, i.e., handling more intricate information and executing wider quantum operations, in complex quantum information technologies (QITs).

Qudit-based high-dimensional controlled-not gate.

High-dimensional quantum systems expand quantum channel capacity and information storage space. By implementing high-dimensional quantum logic gates, the speed of quantum computing can be practically enhanced. We propose a deterministic 4 × 4-dimensional controlled-not (CNOT) gate for a hybrid system without ancillary qudits required, where the spatial and polarization states of a single photon serve as a control qudit of four dimensions, whereas two electron-spin states in nitrogen-vacancy (NV) centers act as a four-dimensional target qudit.

Decoherence-free-subspace-based deterministic conversions for entangled states with heralded robust-fidelity quantum gates.

The decoherence-free subspace (DFS) serves as a protective shield against certain types of environmental noise, allowing the system to remain coherent for extended periods of time. In this paper, we propose two protocols, i.e.

Recent advances and challenges of the use of the CRISPR/Cas system as a non-nucleic acid molecular diagnostic.

The clustered regularly interspaced short palindromic DNA sequence repeats (CRISPR) and CRISPR-associated (Cas) (CRISPR/Cas) systems are currently applied not only as a gene editing tool but also as a novel molecular diagnostic technique. The CRISPR/Cas systems have emerged as an efficient molecular diagnostic system that can detect nucleic acids, proteins and small molecule compounds, by converting a non-nucleic acid into a nucleic acid signal of Cas-identifiable and keeping inherent properties of high sensitivity and specificity. While its multiple advantages for nucleic acid detection have been widely published in excellent reviews, there have been no systematic analyses and reviews on the principles and characteristics of CRISPR/Cas-based diagnostic systems for non-nucleic acids.

[Inhibition of osthole for resorption of rats femur tissue in vitro].

Objective: To investigate osthole effect on femoral tissue resorption activity of rat in vitro.

Methods: Six SD rats weighted (80 ± 5) g were used to isolate and culture femoral tissue (diaphyses and metaphysis) in vitro. The cultured tissue were devided into control group, estradiol group and osthole group.

Coagulation kinetics of humic aggregates in mono- and di-valent electrolyte solutions.

Coagulation behaviors of humic acids (HAs) aggregates in electrolyte solutions at different pHs, valences and concentrations of electrolyte cations were investigated using dynamic light scattering technique in combination of other analytical tools. For monovalent electrolyte sodium chloride (NaCl) solution, at its low concentrations the average hydrodynamic radius () of aggregates kept nearly constant. However, at high NaCl concentrations, could be scaled to the time t as ∝ t(a), suggesting a diffusion-limited colloid aggregation (DLCA).

pH dependence of structure and surface properties of microbial EPS.

The flocculation of microorganisms plays a crucial role in bioreactors, and is substantially affected by pH. However, the mechanism for such an effect remains unclear. In this work, with an integrated approach, the pH dependence of structure and surface property of microbial extracellular polymeric substances (EPS), excreted from Bacillus megaterium TF10, and accordingly its flocculation is elucidated.
