Towards Robust Optimal Measurements Against Noise in Quantum Metrology
Xinglei Yu, Xinzhi Zhao, Liangsheng Li +4
Quantum parameter estimation utilizes quantum mechanical effects to attain higher measurement precision than classical schemes. In practical implementations, however, noise is inev…
Super-resolution microscopy via fluctuation-enhanced spatial mode demultiplexing
Stanislaw Kurdzialek
We introduce a superresolution technique that combines spatial mode demultiplexing (SPADE) with emitter blinking. We show that temporal fluctuations not only enhance the precision…
Optimal phase estimation in the presence of correlated dephasing
Srijon Ghosh, Arkadiusz Kobus, Stanisław Kurdziałek +1
We investigate optimal metrological protocols for phase estimation in the presence of correlated dephasing noise, including spin-squeezed state sensing strategies as well as parall…
QMetro++ -- Python optimization package for large scale quantum metrology with customized strategy structures
Piotr Dulian, Stanisław Kurdziałek, Rafał Demkowicz-Dobrzański
QMetro++ is a Python package that provides a set of tools for identifying optimal estimation protocols that maximize quantum Fisher information (QFI). Optimization can be performed…
Universal bounds for quantum metrology in the presence of correlated noise
Stanislaw Kurdzialek, Francesco Albarelli, Rafal Demkowicz-Dobrzanski
We derive fundamental bounds for general quantum metrological models involving both temporal or spatial correlations (mathematically described by quantum combs), which may be effec…
Quantum metrology using quantum combs and tensor network formalism
Stanislaw Kurdzialek, Piotr Dulian, Joanna Majsak +2
We develop an efficient algorithm for determining optimal adaptive quantum estimation protocols with arbitrary quantum control operations between subsequent uses of a probed channe…
Certifying the quantum Fisher information from a given set of mean values: a semidefinite programming approach
Guillem Müller-Rigat, Anubhav Kumar Srivastava, Stanisław Kurdziałek +3
We introduce a semidefinite programming algorithm to find the minimal quantum Fisher information compatible with an arbitrary dataset of mean values. This certification task allows…
Noise Resistant Phase Imaging with Intensity Correlation
Jerzy Szuniewicz, Stanislaw Kurdzialek, Sanjukta Kundu +4
Interferometric methods, renowned for their reliability and precision, play a vital role in phase imaging. Interferometry typically requires high coherence and stability between th…
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…
Measurement noise susceptibility in quantum estimation
Stanislaw Kurdzialek, Rafal Demkowicz-Dobrzanski
Fisher Information is a key notion in the whole field of quantum metrology. It allows for a direct quantification of maximal achievable precision of estimation of parameters encode…
Back to sources -- the role of losses and coherence in super-resolution imaging revisited
Stanislaw Kurdzialek
Photon losses are intrinsic for any translationally invariant optical imaging system with a non-trivial Point Spread Function, and the relation between the transmission factor and…
Super-resolution Optical Fluctuation Imaging -- fundamental estimation theory perspective
Stanislaw Kurdzialek, Rafal Demkowicz-Dobrzanski
We provide a quantitative analysis of super-resolution imaging techniques which exploit temporal fluctuations of luminosity of the sources in order to beat the Rayleigh limit. We d…
