Suppose we have many copies of an unknown n-qubit state rho. We measure some copies of rho using a known two-outcome measurement E-1, then other copies using a measurement E-2, and so on. At each stage t, we generate a current hypothesis omega(t) about the state rho, using the outcomes of the previous measurements. We show that it is poss...More
