Optimizing quantum process tomography with unitary 2-designs
A. J. Scott
We show that weighted unitary 2-designs define optimal measurements on the system-ancilla output state for ancilla-assisted process tomography of unital quantum channels. Examples…

Weighted complex projective 2-designs from bases: optimal state determination by orthogonal measurements
Aidan Roy, A. J. Scott
We introduce the problem of constructing weighted complex projective 2-designs from the union of a family of orthonormal bases. If the weight remains constant across elements of th…
