An Efficient Quantum Multi-Collision Search Algorithm

IEEE Access, 2020
In this article, we propose an efficient quantum k-collision search algorithm with low quantum memory O(n). The previous quantum k-collision algorithms can not be converted into a low quantum memory k-collision algorithm directly, because the time ...

Time Optimal Control in Spin Systems [PDF]

, 2000
In this paper, we study the design of pulse sequences for NMR spectroscopy as a problem of time optimal control of the unitary propagator. Radio frequency pulses are used in coherent spectroscopy to implement a unitary transfer of state.

Optimizing walking controllers [PDF]

ACM Transactions on Graphics, 2009
This paper describes a method for optimizing the parameters of a physics-based controller for full-body, 3D walking. A modified version of the SIMBICON controller [Yin et al. 2007] is optimized for characters of varying body shape, walking speed and step length. The objective function includes terms for power minimization, angular momentum minimization,

Radial Symmetry and Monotonicity of Solutions to a System Involving Fractional p-Laplacian in a Ball

Advances in Mathematical Physics, 2018
In this paper, we study a nonlinear system involving the fractional p-Laplacian in a unit ball and establish the radial symmetry and monotonicity of its positive solutions. By using the direct method of moving planes, we prove the following result.
