Aug 19, 2021 · We exactly calculate δ αL, as well as the coherent amplitudes of the harmonics, and we confirm experimentally the generation of the ‘cat’ state, by characterizing the quantum …

Mar 17, 2025 · USTC researchers created a long-lived Schrödinger-cat state, boosting quantum metrology and precision measurements. Their findings open new possibilities for quantum …

Jul 15, 2021 · To certify the cat-state entanglement, we employ a tailored, variance-based entanglement criterion, which can robustly detect cat-state entanglement under realistic …

Jan 8, 2021 · In this paper, we consider the state generation by photon number measurement in one mode of two-mode Gaussian states, which is a generalization of conventional photon sub …

Mar 30, 2021 · In particular, "cat states", i.e., two-component macroscopic quantum superpositions, embody quantum coherence in an accessible way and can be harnessed for …

May 3, 2021 · A Schrödinger-cat state is a coherent superposition of macroscopically distinguishable quantum states, in quantum optics usually realized as superposition of …

Abstract. We present an effective method of coherent state superposition (cat state) generation using single trapped ion in a Paul trap. The method is experimentally feasible for coherent …

Unveiling and veiling an entangled light-matter quantum state from the vacuum Phys. Rev. Research 5, 043095 (2023).

analyse the gravitational interaction of a pair of cat states (gravcats), and identify their characteristic behaviors. The detection of gravity-induced entanglement is discussed in …
