    "abstract": "It is shown that mean value of any observable with bounded spectrum can be\nuniquely determined from binary statistics of the measurement performed on {\\it\nsingle} qubit ancilla coupled to a given system. The observable structure is\nfully encoded in the corresponding POVM. The method is generalised to the case\nof distant labs paradigm and discussed in the context of entanglement detection\nwith few local measurements. The results are also discussed in the context of\nquantum programming.",
