Optimal control of quantum state preparation and entanglement creation in two-qubit quantum system with bounded amplitude
Xikun Li
We consider the optimal control problem in a two-qubit system with bounded amplitude. Two cases are studied: quantum state preparation and entanglement creation. Cost functions, fi…
Estimation of optimal control for two-level and three-level quantum systems with bounded amplitude
Xikun Li
A systematic scheme is proposed to numerically estimate the quantum speed limit and temporal shape of optimal control in two-level and three-level quantum systems with bounded ampl…
Optimal error intervals for properties of the quantum state
Xikun Li, Jiangwei Shang, Hui Khoon Ng +1
Quantum state estimation aims at determining the quantum state from observed data. Estimating the full state can require considerable efforts, but one is often only interested in a…
Optimal error regions for quantum state estimation
Jiangwei Shang, Hui Khoon Ng, Arun Sehrawat +2
Rather than point estimators, states of a quantum system that represent one's best guess for the given data, we consider optimal regions of estimators. As the natural counterpart o…
Local Unitary Classification of Arbitrary Dimensional Multipartite Pure States
Bin Liu, Jun-Li Li, Xikun Li +1
We propose a practical entanglement classification scheme for general multipartite pure states in arbitrary dimensions under local unitary equivalence by exploiting the high order…
The Parametric Symmetry and Numbers of the Entangled Class of 2 \times M \times N System
Xikun Li, Junli Li, Bin Liu +1
We present in the work two intriguing results in the entanglement classification of pure and true tripartite entangled state of under stochastic local operation…
