Robust macroscopic Schrödinger's cat on a nucleus [PDF]
Physical Review Research, 2023 We propose a scheme to generate spin cat states, i.e., superpositions of maximally separated quasiclassical states on a single high-dimensional nuclear spin in a solid-state device.

Growing Schrödinger's cat states by local unitary time evolution of product states
Physical Review Research, 2022 We envisage many-body systems described by quantum spin-chain Hamiltonians featuring a trivial separable eigenstate. For generic Hamiltonians, such a state represents a quantum scar.

Fast generation of Schrödinger cat states using a Kerr-tunable superconducting resonator [PDF]
Nature Communications, 2023 Schrödinger cat states, quantum superpositions of macroscopically distinct classical states, are an important resource for quantum communication, quantum metrology and quantum computation.

Engineering Dissipative Channels for Realizing Schrödinger Cats in SQUIDs [PDF]
Frontiers in ICT, 2014 We show that by engineering the interaction with the environment, there exists a large class of systems that can evolve irreversibly to a cat state. To be precise, we show that it is possible to engineer an irreversible process so that the steady state is close to a pure Schrödinger’s cat state by using double well systems and an environment comprising

THE “STATE OF THE ART” OF THE CLAIM IN THE STF AND STJ:IS SCHRÖDINGER'S CAT ALIVE-DEAD?
Revista Eletrônica de Direito Processual, 2021 This article aims to analyze the state of the art of the Constitutional Claim in the Supreme Federal Court and in the Superior Court of Justice, since each court has an understanding about the appropriateness of such an institute.

Entanglement of magnetically levitated massive Schrödinger cat states by induced dipole interaction [PDF]
Physical Review A, 2023 Quantum entanglement provides a novel way to test short-distance quantum physics in a non-relativistic regime. We provide entanglement-based protocols to potentially test the magnetically induced dipole-dipole interaction and the Casimir-Polder potential

Schrödinger cat states of a 16-microgram mechanical oscillator [PDF]
Science, 2022 According to quantum mechanics, a physical system can be in any linear superposition of its possible states. Although the validity of this principle is routinely validated for microscopic systems, it is still unclear why we do not observe macroscopic ...

Observing Schrödinger’s cat with artificial intelligence: emergent classicality from information bottleneck [PDF]
Machine Learning: Science and Technology, 2023 We train a generative language model on the randomized local measurement data collected from Schrödinger’s cat quantum state. We demonstrate that the classical reality emerges in the language model due to the information bottleneck: although our training

Nonreciprocal generation of Schrödinger cat state induced by topology [PDF]
Science China Physics Mechanics and Astronomy, 2023 The Schrödinger cat state produced differently in two directions is anticipated to be a critical quantum resource in quantum information technologies. By exploring the interplay between quantum nonreciprocity and topology in a one-dimensional microcavity

Method to deterministically generate large-amplitude optical cat states [PDF]
Communications Physics, 2023 In quantum physics, superposition—illustrated by Schrödinger’s cat being both dead and alive—inspires ‘cat states’, utilized in quantum technologies. The authors propose a theory where the optical state, through multiple indirect atom interactions in an ...
