We identify a novel qudit gate which we refer to as the gate. This is an alternate
generalization of the qutrit T gate to any odd prime dimension d, in the dth level of the …

We present a comprehensive investigation into the learning capabilities of a simple d-level
system (qudit). Our study is specialized for classification tasks using real-world databases …
