Using parametric conversion induced by a Shapiro-type resonance, we produce and
characterize a two-mode squeezed vacuum state in a sodium spin 1 Bose–Einstein …

We study experimentally the equilibrium phase diagram of a spin-1 Bose-Einstein
condensate with antiferromagnetic interactions, in a regime where spin and spatial degrees …

We introduce a semidefinite programming algorithm to find the minimal quantum Fisher
information compatible with an arbitrary dataset of mean values. This certification task allows …

The past few decades have seen dramatic progress in our ability to manipulate and
coherently control matter-waves. Although the duality between particles and waves has …

We demonstrate dynamic stabilization of a strongly interacting quantum spin system realized
in a spin-1 atomic Bose-Einstein condensate. The spinor Bose-Einstein condensate is …

Multipartite entanglement, such as witnessed through the quantum Fisher information (QFI),
is a crucial resource for quantum technologies, but its experimental certification is highly …

Quantifying quantum mechanical uncertainty is vital for the increasing number of
experiments that reach the uncertainty limited regime. We present a method for computing …

We use a one-dimensional optical lattice to modify the dispersion relation of atomic matter
waves. Four-wave mixing in this situation produces atom pairs in two well-defined beams …

Entanglement is typically created via systematic intervention in the time evolution of an
initially unentangled state, which can be achieved by coherent control, carefully tailored …

We have experimentally observed the emergence of spontaneous antiferromagnetic spatial
order in a sodium spinor Bose-Einstein condensate that was quenched through a magnetic …
