Note on Exchange Gate on the Qudit Space
Kazuyuki Fujii · arXiv (Cornell University) · 2002
We construct the exchange gate with small elementary gates on the space of qudits, which consist of three controlled shift gates and three "reverse" gates. This is a natural extension of the qubit case. We also consider a similar subject on the Fock space, but in this case it is not clear what elementary gates are. We present some related problems.
