Finite-Shot Sensitivity for Moment Estimation in Quantum Metrology
Shaowei Du, Shuheng Liu, Weidong Li +3
The quantum Cramér-Rao bound can be saturated only asymptotically and does not specify how many measurements are needed for a concrete estimator to approach it. We develop a finit…
Hong-Ou-Mandel interference of more than 10 indistinguishable atoms
Martin Quensen, Mareike Hetzel, Luis Santos +4
When two indistinguishable bosons interfere at a beam splitter, they both exit through the same output port. This foundational quantum-mechanical phenomenon, known as the Hong-Ou-M…
Robust multipartite entanglement in dirty topological wires
Luca Pezzè, Luca Lepori
Identifying and characterizing quantum phases of matter in the presence of long range correlations and/or spatial disorder is, generally, a challenging and relevant task. Here, we…
Quantum Chaos, Randomness and Universal Scaling of Entanglement in Various Krylov Spaces
Hai-Long Shi, Augusto Smerzi, Luca Pezzè
Multipartite entanglement is a crucial resource for advancing quantum technologies, with considerable research efforts directed toward achieving its rapid and scalable generation.…
Scalable Network of Mach-Zehnder Interferometers with a Single Entangled Resource
Zhihui Yan, Yanni Feng, Luca Pezze +6
Distributed quantum sensing exploits entanglement to enhance the estimation of multiple parameters across a network of spatially-separated sensors, achieving sensitivities beyond t…
Joint estimation of phase and uncorrelated dephasing in a differential quantum interferometer
Luca Pezzè, Andrea Santoni, Chiara Mazzinghi +2
Precise measurements in optical and atomic systems often rely on differential interferometry. This method allows to handle large and correlated phase noise contributions -- such as…
