Interplay between time and energy in bosonic noisy quantum metrology
Wojciech Górecki, Francesco Albarelli, Simone Felicetti +2
Quantum entanglement and coherence often allow for protocols that outperform classical ones in estimating a system's parameter. When using infinite-dimensional probes (such as a bo…
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…
-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…
