We generate spin squeezed ground states in an atomic spin-1 Bose-Einstein condensate
tuned near the quantum-critical point separating the different spin phases of the interacting …

We spatially expand and subsequently contract the motional thermal state of a levitated
nanoparticle using a hybrid trapping scheme. The particle's center-of-mass motion is …

We show experimentally that a broad class of interactions involving quantum harmonic
oscillators can be made stronger (amplified) using a unitary squeezing protocol. While our …

The generation of mechanical squeezing has attracted a lot of interest for its nonclassical
properties, applications in quantum information and high-sensitivity measurements. Here we …

Two-mode squeezed states, which are entangled states with bipartite quantum correlations
in continuous-variable systems, are crucial in quantum information processing and …

The ground state of the quantum Rabi model (QRM) exhibits rich nonclassical states
including the squeezed state, cat state, and entangled state in different parameter regimes …

Squeezing is a crucial resource for quantum information processing and quantum sensing.
In levitated nanomechanics, squeezed states of motion can be generated via temporal …

We study the effect of the intermode coupling in the generation of coherence when two
bosonic modes are bilinearly coupled. We consider the case for which the two modes are …

Harmonic oscillators with multiple abrupt jumps in their frequencies have been investigated
by several authors during the last decades. We investigate the dynamics of a quantum …

In quantum metrology, one typically creates correlations among atoms or photons to
enhance measurement precision. Here, we show how one can use other excitations to …
