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

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 …

Superpositions of macroscopically distinct quantum states, introduced in Schrödinger's
famous Gedankenexperiment, are an epitome of quantum 'strangeness' and a natural tool …

We propose a high-rate generation method of optical Schrödinger cat states. Thus far,
photon subtraction from squeezed vacuum states has been a standard method in cat-state …

Remote state preparation enables one to prepare and manipulate quantum state non‐
locally. As an essential quantum resource, optical cat state is usually prepared locally by …

The use of quantum resources can provide measurement precision beyond the shot-noise
limit (SNL). The task of ab initio optical phase measurement—the estimation of a completely …

Light is an irreplaceable means of communication among various quantum information
processing and storage devices. Due to their different physical nature, some of these …

The transfer of quantum information between physical systems of a different nature is a
central matter in quantum technologies. Particularly challenging is the transfer between …

We present an algorithm of quantum engineering of large-amplitude≥ 5 high-fidelity≥ 0.99
even/odd Schrödinger cat states (SCSs) using a single mode squeezed vacuum (SMSV) …

Quantum phenomena such as entanglement can improve fundamental limits on the
sensitivity of a measurement probe. In optical interferometry, a probe consisting of N …
