Multi-parameter estimation beyond Quantum Fisher Information
Rafal Demkowicz-Dobrzanski, Wojciech Gorecki, Madalin Guta
This review aims at gathering the most relevant quantum multi-parameter estimation methods that go beyond the direct use of the Quantum Fisher Information concept. We discuss in de…
Strongly correlated quantum droplets in quasi-1D dipolar Bose gas
Rafał Ołdziejewski, Wojciech Górecki, Krzysztof Pawłowski +1
We exploit a few- to many-body approach to study strongly interacting dipolar bosons in the quasi-one-dimensional system. The dipoles attract each other while the short range inter…
-Corrected Heisenberg Limit
Wojciech Gorecki, Rafal Demkowicz-Dobrzanski, Howard M. Wiseman +1
We consider the precision with which the parameter , appearing in the unitary map acting on some type of probe system, can be estimated when there is a fin…
Optimal probes and error-correction schemes in multi-parameter quantum metrology
Wojciech Gorecki, Sisi Zhou, Liang Jiang +1
We derive a necessary and sufficient condition for the possibility of achieving the Heisenberg scaling in general adaptive multi-parameter estimation schemes in presence of Markovi…
