An infinite family of strongly unextendible mutually unbiased bases in ${\mathbb{C}}^{2^{2h}}$

Jonathan Jedwab, Lily Yen

A set of $b$ mutually unbiased bases (MUBs) in ${\mathbb{C}}^d$ (for $d>1$) comprises $bd$ vectors in ${\mathbb{C}}^d$, partitioned into $b$ orthogonal bases for ${\mathbb{C}}^d$ such…
