Measurement compatibility in multiparameter quantum interferometry
Jayanth Jayakumar, Marco Barbieri, Magdalena StobiÅska
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. Differe…
Experimental neuromorphic computing based on quantum memristor
Mirela SelimoviÄ, Iris Agresti, MichaÅ Siemaszko +8
Machine learning has recently developed novel approaches, mimicking the synapses of the human brain to achieve similarly efficient learning strategies. Such an approach retains the…
Ultra-robust topologically protected edge states in quasi-1D systems
Valerii Kachin, Juan Camilo López Carreño, Magdalena StobiÅska
In recent years, the study of topologically non-trivial structures in one-dimensional models has been dominated by the Su--Schrieffer--Heeger model due to its simplicity in design…
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…
