Measurement compatibility in multiparameter quantum interferometry
Jayanth Jayakumar, Marco Barbieri, Magdalena Stobińska
The Cramér-Rao bound captures completely the performance of single-parameter quantum sensors. On the other hand, its extension to multiple parameters demands more caution. Differen…
Quantum-enhanced joint estimation of phase and phase diffusion
Jayanth Jayakumar, Monika E. Mycroft, Marco Barbieri +1
Accurate phase estimation in the presence of unknown phase diffusive noise is a crucial yet challenging task in noisy quantum metrology. This problem is particularly interesting du…
Interference-induced localization in quantum random walk on clean cyclic graph
Jayanth Jayakumar, Sreetama Das, Aditi Sen De +1
We quantitatively differentiate between the spreads of discrete-time quantum and classical random walks on a cyclic graph. Due to the closed nature of any cyclic graph, there is ad…
