    "abstract": "We consider the problem of optimal asymptotically faithful compression for\nensembles of mixed quantum states. Although the optimal rate is unknown, we\nprove upper and lower bounds and describe a series of illustrative examples of\ncompression of mixed states. We also discuss a classical analogue of the\nproblem.",
