摘要： Systems and methods are provided for implementing arbitrary single-qubit quantum gates using sequences of single-qubit quantum gates. The systems and methods can implement a first quantum gate in a gate sequence by applying a first sequence of phase-shifted pulses to the qubit. After applying the first quantum gate, a second quantum gate in the gate sequence can be implemented by applying a second sequence of phase-shifted pulses to the qubit. The implementation of the second quantum gate can introduce an additional rotation. This additional rotation can be independent of the implementation of the first quantum gate. A pulse in the second sequence can be configured to implement: a virtual Z gate having a first rotation angle; an X gate having a second rotation angle; and the virtual Z gate having a negative of the first rotation angle.

摘要： One embodiment described herein provides a system and method for adjusting the relay state of nodes in a wireless network. During operation, the system can obtain relay-state information associated with a plurality of neighboring nodes of a respective node in the wireless network. The system can identify, among the plurality of neighboring nodes, a set of relay neighbors capable of relaying messages based on the obtained relay-state information and determine a connectivity status of the set of relay neighbors. The system can then determine an expected relay state of the respective node based on a count and the connectivity status of the set of relay neighbors and can adjust a relay state of the respective node based on the expected relay state.

摘要： Systems and methods implement a modular computing environment for Bayesian optimization, decoupling steps of Bayesian optimization across multiple modules; minimizing inter-module dependency; extending functionality of each module; and reusing computing resources and intermediate results within each module. Variable hyperparameterization may reduce computational costs of optimization iterations, while also averting overfitting and destabilization of the Gaussian kernel based on sparser observations of the objective function. Computational complexity of updating the Gaussian kernel may be reduced from the cube to the square of the set of sampled outputs, by deferring computing updates to each hyperparameter while the optimization iterations are ongoing. Furthermore, repeated allocation and release of memory, repeated writing of data in memory to non-volatile storage, and repeated reading of data in non-volatile storage to memory across multiple optimization iterations may be averted, thereby alleviating multiple categories of computing resources, including processing power, memory, storage, from excess performance load.

摘要： Embodiments of the present application provide an interaction method, system and electronic device. The method includes: playing an audio/video; displaying an interactive control reflecting a playback progress in a playback interface of the audio/video; determining, in response to an interactive operation triggered by a user through the interactive control, interaction information and the playback progress when the interactive operation is triggered; and sending, based on the interaction information and the playback progress, the user's interaction data for audio/video segments to a server terminal, to enable the server terminal to obtain respective interaction data triggered by different users for different segments of the audio/video. Using the technical solutions provided by the present application, users can interact with one or multiple segments of an audio/video, which will help to obtain user interaction popularities for different segments, guide the users to watch or listen, and reduce the probability of missing exciting segments. In addition, to a certain extent, this will also help improve indicators such as the number of times of playing audio/video and the number of playing content, etc.
