We discuss various methods to create macroscopic (bright) entangled light beams. As an
example, bright squeezed vacuum is considered in detail. This state of light, obtained via …

Schrödinger's famous thought experiment involves a (macroscopic) cat whose quantum
state becomes entangled with that of a (microscopic) decaying nucleus. The creation of such …

We present a review and discussions on characterizations and quantifications of
macroscopic quantum states as well as their implementations and applications in optical …

We propose to create and detect optomechanical entanglement by storing one component
of an entangled state of light in a mechanical resonator and then retrieving it. Using micro …

The quantum Fisher information and quantum correlation parameters are employed to study
the application of nonclassical light to the problem of parameter estimation. It is shown that …

Mesoscopic superposition states of photons can be prepared in three cavities interacting
with the same two-level atom. By periodically modulating the three cavity frequencies …

We derive an analytical description for quantum state preparation using systems of on-off
detectors. Our method will apply the true click statistics of such detector systems. In …

We propose to create superposition states of over 100 strontium atoms in a ground state or
metastable optical clock state using the Kerr-type interaction due to Rydberg state dressing …

We propose a scheme to generate entanglement between a single-photon qubit in the
polarization basis and a coherent state of light. The required resources are a superposition …

A method for performing nonlocal interferometry using phase-entangled macroscopic
coherent states is described. The required entanglement can be generated using weak …
