Multipartite entangled states, symmetric matrices and error-correcting codes
Keqin Feng, Lingfei Jin, Chaoping Xing +1
A pure quantum state is called -uniform if all its reductions to -qudit are maximally mixed. We investigate the general constructions of -uniform pure quantum states of $n…
A Construction of Linear Codes over $\f_{2^t}$ from Boolean Functions
Can Xiang, Keqin Feng, Chunming Tang
In this paper, we present a construction of linear codes over $\f_{2^t}$ from Boolean functions, which is a generalization of Ding's method \cite[Theorem 9]{Ding15}. Based on this…
Nonexistence of Generalized Bent Functions From to
Haiying Liu, Keqin Feng, Rongquan Feng
Several nonexistence results on generalized bent functions presented by using some knowledge on cyclotomic number fields and their imaginary quadrat…
Relative Generalized Hamming Weights of Cyclic Codes
Jun Zhang, Keqin Feng
Relative generalized Hamming weights (RGHWs) of a linear code respect to a linear subcode determine the security of the linear ramp secret sharing scheme based on the code. They ca…
