Query: General Measurements with Limited Resources and Their Application to
  Quantum Unambiguous State Discrimination   In this report we present a framework for implementing arbitrary $n$-outcome
quantum measurement as a sequence of two-outcome measurements requiring only
single ancillary qubit. Our procedure is the same as one presented in [Phys.
Rev. A 77, 052104 (2008)] but in addition offers particular construction for a
two-outcome partial measurements. We exemplify this framework on the
unambiguous state discrimination. In the simplest case it gives the same
construction as is known, if we opt for performing conclusiveness measurement
first. However, it also offers possibility of performing measurement for one of
the state outcomes, which shows flexibility of presented framework.
