Abstract Electronic sensors play important roles in various applications, such as industry and environmental monitoring, biomedical sample ingredient analysis, wireless networks so on. However, the sensitivity robustness of current schemes are often limited by low quality‐factors resonators fabrication disorders. Hence, exploring new mechanisms electronic sensor with a high‐level strong is great significance. Here, way to design superior performances based on exotic properties non‐Hermitian...
Quantum search algorithm, which can an unsorted database quadratically faster than any known classical algorithms, has become one of the most impressive showcases quantum computation. It been implemented using various schemes. Here, we demonstrate both theoretically and experimentally that such a fast algorithm also be realized electric circuits. The circuit networks to perform have designed. shown evolution signals in is analogies particles randomly walking on graphs described by theory....
The key obstacle to the realization of a scalable quantum computer is overcoming environmental and control errors. Topological computation attracts great attention because it emerges as one most promising approaches solving these problems. Various theoretical schemes for building topological have been proposed. However, experimental implementation has always challenge proved be extremely difficult create manipulate qubits in real systems. Therefore, not realized experiments yet. Herein,...
Abstract Recently, higher-order topological insulators (HOTIs) have been introduced, and were shown to host corner states under the theoretical framework of Benalcazar-Bernevig-Hughes. Here we unveil some effects in HOTIs by studying three-dimensional (3D) non-Abelian Bloch oscillations (BOs). In HOTIs, BOs with a multiplied period occur when force special direction is applied due effect Berry curvature. Along find state that goes beyond multipole moments. The emergence such coincides...
Abstract The ultimate goal of developing quantum algorithms and constructing computers is to achieve faster information processing than using current classical computers. Quantum walks are powerful kernels in computing protocols possess strong capabilities speeding up various simulation optimization tasks. One striking example provided by walkers evolving on unbalanced trees, which demonstrate hitting performances random walk. However, direct experimental construction trees prove advantage...
Compared with classical algorithms, quantum algorithms can show the advantage of exponential speedup in solving some problems. Solving NAND‐Tree problem is a typical example, which be speed up exponentially by walk. This scheme groundbreaking due to universality negative‐AND (NAND) gate. In fact, NAND gate also universal for computation, making it an important target development. Herein, onto circuit network mapped and new type logic that perform designed. These gates are designed have...
