Jarlskog's Parametrization of Unitary Matrices and Qudit Theory
Kazuyuki Fujii, Kunio Funahashi, Takayuki Kobayashi
In the paper (math-ph/0504049) Jarlskog gave an interesting simple parametrization to unitary matrices, which was essentially the canonical coordinate of the second kind in the Lie…

The Controlled-U and Unitary Transformation in Two-Qudit
Kunio Funahashi
We concretely construct an extension of the controlled-U gate in qudit from some elementary gates. We also construct unitary transformation in two-qudit by means of the extended co…
