Entanglement quantification in atomic ensembles
Matteo Fadel, Ayaka Usui, Marcus Huber +2
Entanglement measures quantify nonclassical correlations present in a quantum system, but can be extremely difficult to calculate, even more so, when information on its state is li…
Nuclear spin squeezing in Helium-3 by continuous quantum nondemolition measurement
Alan Serafin, Matteo Fadel, Philipp Treutlein +1
We propose a technique to control the macroscopic collective nuclear spin of a Helium-3 vapor in the quantum regime using light. The scheme relies on metastability exchange collisi…
Nuclear spin squeezing by continuous quantum non-demolition measurement: a theoretical study
Alan Serafin, Yvan Castin, Matteo Fadel +2
We propose to take advantage of the weak coupling of ground-state helium-3 nuclear spin to its environment to produce long-lived macroscopic quantum states, nuclear spin squeezed s…
Bounding the fidelity of quantum many-body states from partial information
Matteo Fadel, Albert Aloy, Jordi Tura
We formulate an algorithm to lower bound the fidelity between quantum many-body states only from partial information, such as the one accessible by few-body observables. Our method…
Normalized Gaussian Path Integrals
Giulio Corazza, Matteo Fadel
Path integrals play a crucial role in describing the dynamics of physical systems subject to classical or quantum noise. In fact, when correctly normalized, they express the probab…
Fundamental limit of phase coherence in two-component Bose-Einstein condensates
Yifan Li, Krzysztof Pawłowski, Boris Décamps +4
We experimentally and theoretically study phase coherence in two-component Bose-Einstein condensates of atoms on an atom chip. Using Ramsey interferometry we measur…
