Generation of Schrödinger cat states with Wigner negativity using a continuous-wave low-loss waveguide optical parametric amplifier. [PDF]
Optics Express, 2022 Continuous-wave (CW) squeezed light is used in the generation of various optical quantum states, and thus is a fundamental resource of fault-tolerant universal quantum computation using optical continuous variables.

Critical Schrödinger Cat Qubit [PDF]
PRX Quantum, 2022 Encoding quantum information onto bosonic systems is a promising route to quantum error correction. In a cat code, this encoding relies on the confinement of the system's dynamics onto the two-dimensional manifold spanned by Schr\"odinger cats of ...

The place of preservation of the false : mistakes, accidents and homonyms in the novel "Sand" by Wolfgang Herrndorf [PDF]
, 2013 This paper aims to examine Wolfgang Herrndorf's novel "Sand" (2011), taking into consideration its concatenation of errors, accidents and the logic of the absurd. The first part of this investigation regards the different connotations of the desert motif

Dynamical entropic measure of nonclassicality of phase-dependent family of Schrödinger cat states
Scientific Reports, 2023 The phase-space approach based on the Wigner distribution function is used to study the quantum dynamics of the three families of the Schrödinger cat states identified as the even, odd, and Yurke–Stoler states.

A flying Schrödinger’s cat in multipartite entangled states [PDF]
Science Advances, 2021 Schrödinger’s cat originates from the famous thought experiment querying the counterintuitive quantum superposition of macroscopic objects. As a natural extension, several “cats” (quasi-classical objects) can be prepared into coherent quantum ...

Area law from loop quantum gravity [PDF]
, 2018 We explore the constraints following from requiring the area law in the entanglement entropy in the context of loop quantum gravity. We find a unique solution to the single-link wave function in the large j limit, believed to be appropriate in the ...

Engineering entangled Schrödinger cat states of separated cavity modes in cavity QED [PDF]
Physical Review AWe provide a scheme by utilizing a two-cavity setup to generate useful quantum mechanically entangled states of two cavity fields, which themselves are prepared in Schrodinger cat states.

Preparation of Schrödinger cat quantum state using parametric down-conversion interaction [PDF]
Journal of the Optical Society of America BThe Schr\"odinger cat (SC) states are important in quantum optics because of their non-Gaussian properties. We propose a novel method of conditional generation of bright (multi-photon) SC states that uses degenerate parametric down-conversion and ...

Using Schrödinger cat quantum state for detection of a given phase shift [PDF]
Laser Physics LettersWe show that injecting a light pulse prepared in the Shrödinger cat quantum state into the dark port of a two-arm interferometer, it is possible to detect a given phase shift unambiguously.
