    • It has recently come to our attention that a particular choice of 4l+1 measurement directions was proposed as early as 1968 by R. G. Newton and B.-L. Young, Ann. Phys. (N.Y.) 49, 393 (1968). The results in this paper show that 4l+1 measurement directions are also sufficient for quantum tomography. However, Newton and Young suggested that a better choice of directions could reduce the number of measurement directions needed. Our results show that this is in fact impossible.

    • 2l〉 itself is a consequence of the fact that the discreteness of the quantized eigenvalues makes a higher resolution unnecessary.
