This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Advanced quantum technologies require scalable and controllable quantum resources,.
Gaussian states of multimode light, such as squeezed states and cluster states, are scalable …

The ability to manipulate light at the level of single photons, its elementary excitation quanta,
has recently made it possible to produce a rich variety of tailor-made quantum states and …

The optical cat state plays an essential role in quantum computation and quantum
metrology. Here, we experimentally quantify quantum coherence of an optical cat state by …

We theoretically demonstrate through numerical methods that the triple-photon state
generated by three-photon spontaneous parametric down-conversion is a non-Gaussian …

In this paper, we present the theoretical framework of quantum speed limits (QSLs) in terms
of trajectory ensembles in phase space. This indicates that the QSL can be thought of as the …

We present a scheme of quantum repeater that uses entangled multimode coherent states
that are obtained by electro-optic modulation of symmetric and antisymmetric Schrödinger …

We propose a scheme to generate the macroscopic entangled Schrödinger cat state of two
mechanical resonators in a hybrid optomechanical system by introducing modulated photon …

Homodyne measurements are a widely used quantum measurement. Using a coherent state
of large amplitude as the local oscillator, it can be shown that the quantum homodyne …
