Phys. Rev. A 91, 042126 (2015)      Jul 2014
Quantum metrology is a general term for methods to precisely estimate the
value of an unknown parameter by actively using quantum resources. In
particular, some classes of entangled states can be used to significantly
suppress the estimation error...

Phys. Rev. Lett. 111, 160406 (2013)      Jun 2013
Quantum state tomography is the standard tool in current experiments for
verifying that a state prepared in the lab is close to an ideal target state,
but up to now there were no rigorous methods for evaluating the precision of
the state preparati...

New J. Phys. 14, 085005 (2012)      May 2012
We analyze the behavior of estimation errors evaluated by two loss functions,
the Hilbert-Schmidt distance and infidelity, in one-qubit state tomography with
finite data. We show numerically that there can be a large gap between the
estimation err...

We consider 1-qubit mixed quantum state estimation by adaptively updating
measurements according to previously obtained outcomes and measurement
settings. Updates are determined by the average-variance-optimality
(A-optimality) criterion, known in...

Phys. Rev. A 83, 012105 (2011)      Sep 2010
We expand the scope of the statistical notion of error probability, i.e., how
often large deviations are observed in an experiment, in order to make it
directly applicable to quantum tomography. We verify that the error probability
can decrease at...
