Bush-type Butson Hadamard matrices
View through CrossRef
Bush-type Butson Hadamard matrices are introduced. It is shown that a
nonextendable set of mutually unbiased Butson Hadamard matrices is obtained by
adding a specific Butson Hadamard matrix to a set of mutually unbiased
Bush-type Butson Hadamard matrices. A class of symmetric Bush-type Butson
Hadamard matrices over the group \(G\) of \(n\)-th roots of unity is introduced that
is also valid over any subgroup of \(G\). The case of Bush-type Butson Hadamard
matrices of even order will be discussed.
