Metrological Nonlinear Squeezing Parameter
Manuel Gessner, Augusto Smerzi, Luca Pezzè
The well known metrological linear squeezing parameters (such as quadrature or spin squeezing) efficiently quantify the sensitivity of Gaussian states. Yet, these parameters are in…
Motional Fock states for quantum-enhanced amplitude and phase measurements with trapped ions
Fabian Wolf, Chunyan Shi, Jan C. Heip +6
Non-vanishing fluctuations of the vacuum state are a salient feature of quantum theory. These fluctuations fundamentally limit the precision of quantum sensors. Nowadays, several s…
Sensitivity Bounds for Multiparameter Quantum Metrology
Manuel Gessner, Luca Pezzè, Augusto Smerzi
We identify precision limits for the simultaneous estimation of multiple parameters in multimode interferometers. Quantum strategies to enhance the multiparameter sensitivity are b…
Frequentist and Bayesian Quantum Phase Estimation
Yan Li, Luca Pezzè, Manuel Gessner +2
Frequentist and Bayesian phase estimation strategies lead to conceptually different results on the state of knowledge about the true value of the phase shift. We compare the two fr…
Characterizing the multipartite continuous-variable entanglement structure from squeezing coefficients and the Fisher information
Zhongzhong Qin, Manuel Gessner, Zhihong Ren +6
Understanding the distribution of quantum entanglement over many parties is a fundamental challenge of quantum physics and is of practical relevance for several applications in the…
Hyper- and hybrid nonlocality
Yanna Li, Manuel Gessner, Weidong Li +1
The controlled generation and identification of quantum correlations, usually encoded in either qubits or continuous degrees of freedom, builds the foundation of quantum informatio…
