We propose a scheme for achieving basic quantum gates using ultracold polar molecules in pendular states. The qubits are encoded the YbF trapped an electric field with certain gradient and coupled by dipole–dipole interaction. time-dependent control sequences consisting of multiple pulses considered to interact qubits. To achieve high-fidelity gates, we map problem molecular system into Markov decision process deal it techniques deep reinforcement learning (DRL). By training agents over...

Abstract Early augmented reality (AR) community has paid a lot of attention to identifying 2D fiducial markers in AR scene, only little works have been devoted 3D objects perception. With the massively increased usage representation, it is highly desirable that powerful processing tools and algorithms should be developed for recognition purpose domain. In this paper, we address depth understanding problem assembly applications. We propose registration based perception method designed desk...

Implementation of quantum gates are important for computations in physical system made polar molecules. We investigate the feasibility implementing based on pendular states molecular by two different optical control methods. Firstly, Multi-Target optimal theory and Multi-Constraint described optimizing fields accomplish optimization gates. Numerical results show that controlled NOT gate (CNOT) can be realized under above methods with high fidelities (0.975 0.999) respectively. In addition,...

A new mobile computing model of spatial information service is studied based on grid environment. Key technologies are presented in the model, including agent (MA) computing, location (LBS), global positioning system (GPS), and wireless communication technologies, such as, general packet radio (GPRS), transfer control protocol/Internet protocol (TCP/IP), user datagram (UDP). In order to deal with narrow bandwidth instability Internet, distributed organization tremendous data, limited...

With the Internet and Intranet popularization broadband technology development, number of network node in large medium-scale enterprise's or university's is increasingly swift increase. But, virus attacks, especially, such as loop, ARP spoofing DHCP attack result fault frequently happened, even cause paralysis. For solving these troubles, it not only consumes a lot time manpower management department, but also delays user to use network. Thus, department hopes overcome solve problems...

Agriculture is the foundation of national economy. The periodicity agricultural product output and prices, asymmetry information between buyers sellers, inherent characteristics small scale, high cost, low profit have caused slow sales, which greatly hurt enthusiasm farmers to develop production endanger social stability. Constructing an informationized commercialized trading platform sharing through e-commerce establishing related systems supervision mechanisms will help promote rapid...

How to get more realistic model is important for a virtual arthroscopic knee surgery training system. A method of 3-D reconstruction from the CT images given. This selects appropriate threshold segmentation, according histogram image sequence. Then further processes with region growing segmentation. Finally, we accurate models.
