Quantum squeezing in a nonlinear mechanical oscillator
Stefano Marti, Uwe von Lüpke, Om Joshi +5
Mechanical degrees of freedom are natural candidates for continuous-variable quantum information processing and bosonic quantum simulations. These applications, however, require th…
Assisted metrology and preparation of macroscopic superpositions with split spin-squeezed states
Jiajie Guo, Fengxiao Sun, Qiongyi He +1
We analyse the conditional states in which one part of a split spin-squeezed state is left, upon performing a collective spin measurement on the other part. For appropriate measure…
Probing gravity-related decoherence with a 16 g Schrödinger cat state
Matteo Fadel
The Schrödinger equation predicts the validity of the superposition principle at any scale, yet we do not experience cats being in a superposition of "dead" and "alive" in our ever…
Detecting Bell correlations in multipartite non-Gaussian spin states
Jiajie Guo, Jordi Tura, Qiongyi He +1
We expand the toolbox for studying Bell correlations in multipartite systems by introducing permutationally invariant Bell inequalities (PIBIs) involving few-body correlators. Firs…
Engineering phonon-phonon interactions in multimode circuit quantum acousto-dynamics
Uwe von Lüpke, Ines C. Rodrigues, Yu Yang +2
In recent years, remarkable progress has been made towards encoding and processing quantum information in the large Hilbert space of bosonic modes. Mechanical resonators are of gre…
Probing quantum correlations in many-body systems: a review of scalable methods
Irénée Frérot, Matteo Fadel, Maciej Lewenstein
We review methods that allow one to detect and characterise quantum correlations in many-body systems, with a special focus on approaches which are scalable. Namely, those applicab…
