A twofold quantum delayed-choice experiment in a superconducting circuit

2017 · Science Advances

Wave-particle complementarity lies at the heart of quantum mechanics. To illustrate this mysterious feature, Wheeler proposed the delayed-choice experiment, where a quantum system manifests the wave- or particle-like attribute, depending on the experimental arrangement, which …

High-fidelity, high-scalability two-qubit gate scheme for superconducting qubits

2020 · arXiv (Cornell University)

High-quality two-qubit gate operations are crucial for scalable quantum information processing. Often, the gate fidelity is compromised when the system becomes more integrated. Therefore, a low-error-rate, easy-to-scale two-qubit gate scheme is highly desirable. Here, we …

Experimental Simulation of Open Quantum System Dynamics via Trotterization

2021 · Physical Review Letters

Digital quantum simulators provide a diversified tool for solving the evolution of quantum systems with complicated Hamiltonians and hold great potential for a wide range of applications. Although much attention is paid to the unitary …

Suppressing Coherent Two-Qubit Errors via Dynamical Decoupling

2021 · Physical Review Applied

Scalable quantum information processing requires the ability to tune multiqubit interactions. This makes the precise manipulation of quantum states particularly difficult for multiqubit interactions because tunability unavoidably introduces sensitivity to fluctuations in the tuning parameters, …

Cement Quality Management and Analysis System Development

2022 · 2022 37th Youth Academic Annual Conference of Chinese Association of Automation (YAC)

This paper provides a detailed description of the cement quality management and analysis system. The use of SQL database is more standardized to establish a unified platform for cement plant data, and the client system …

Spatial Target Tracking Algorithm Based on Heterogeneous Sensors Data Fusion

2023

The track of Spatial targets is basically non-linear, which makes the cost of using homogeneous sensors for space target tracking significantly increase. Data fusion using heterogeneous sensors can achieve information complementarity, thereby improving recognition ability. …

ICAI-SR: Item Categorical Attribute Integrated Sequential Recommendation

2021

Sequential recommendation (SR) has attracted much research attention in the past few years. Most existing attribute integrated SR models do not directly model the complex relations between items and categorical attributes, as well do not …
