Protecting Heisenberg scaling in quantum metrology via engineered dressed states

Wojciech Gorecki, Christiane P. Koch

Quantum metrology promises precision beyond classical limits but environmental noise, unless properly controlled, reduces the quantum advantage to at most a constant improvement. A…

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…

Universal time scalings of sensitivity in Markovian quantum metrology

Arpan Das, Wojciech Gorecki, Rafal Demkowicz-Dobrzanski

Assuming Markovian time evolution of a quantum sensing system, we study the general characterization of the optimal sensitivity scalings with time, under most general quantum contr…

Using adaptiveness and causal superpositions against noise in quantum metrology

Stanislaw Kurdzialek, Wojciech Gorecki, Francesco Albarelli +1

We derive new bounds on achievable precision in the most general adaptive quantum metrological scenarios. The bounds are proven to be asymptotically saturable and equivalent to the…

Quantum metrology of noisy spreading channels

Wojciech Górecki, Alberto Riccardi, Lorenzo Maccone

We provide the optimal measurement strategy for a class of noisy channels that reduce to the identity channel for a specific value of a parameter (spreading channels). We provide a…

Multiple-phase quantum interferometry -- real and apparent gains of measuring all the phases simultaneously

Wojciech Gorecki, Rafal Demkowicz-Dobrzanski

We characterize operationally meaningful quantum gains in a paradigmatic model of lossless multiple-phase interferometry and stress insufficiency of the analysis based solely on th…

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…
