    "abstract": "It is known that mutually unbiased bases, whenever they exist, are optimal in\nan information theoretic sense for the determination of unknown state of a\nquantum ensemble. These bases may not exist in most dimensions and some\nsuboptimal choices have to be made. The present paper deals with estimates of\nthe information loss in suboptimal choice of bases. The information is\ncalculated directly in terms of transition probabilities. I give estimates for\nthe information content of measurement in some approximate MUBs proposed\nrecently.",
