Incompatibility probability of random quantum measurements
Lin Zhang, Hua Xiang, Xianqing Li-Jost +1
Incompatibility of quantum measurements is of fundamental importance in quantum mechanics. It is closely related to many nonclassical phenomena such as Bell nonlocality, quantum un…
Quantum algorithm for total least squares data fitting
Hefeng Wang, Hua Xiang
The total least squares~(TLS) method is widely used in data-fitting. Compared with the least squares fitting method, the TLS fitting takes into account not only observation errors,…
Singular Values of Riemann Curvature Tensor
Xiaokai He, Hua Xiang
We introduce the concept of singular values for the Riemann curvature tensor, a central mathematical tool in Einstein's theory of general relativity. We study the properties relate…
Quantum Circulant Preconditioner for Linear System of Equations
Changpeng Shao, Hua Xiang
We consider the quantum linear solver for with the circulant preconditioner . The main technique is the singular value estimation (SVE) introduced in [I. Kerenidis and A.…
M-eigenvalues of The Riemann Curvature Tensor
Hua Xiang, Liqun Qi, Yimin Wei
The Riemann curvature tensor is a central mathematical tool in Einstein's theory of general relativity. Its related eigenproblem plays an important role in mathematics and physics.…
On the M-eigenvalues of elasticity tensor and the strong ellipticity condition
Hua Xiang, Liqun Qi, Yimin Wei
Strong ellipticity is an important property in the elasticity theory. In 2009, M-eigenvalues were introduced for the elasticity tensor. It was shown that M-eigenvalues are invarian…
