Schrödinger cat states of a 16-microgram mechanical oscillator
Marius Bild, Matteo Fadel, Yu Yang +4
The superposition principle is one of the most fundamental principles of quantum mechanics. According to the Schrödinger equation, a physical system can be in any linear combinatio…
Macroscopic quantum test with bulk acoustic wave resonators
Björn Schrinski, Yu Yang, Uwe von Lüpke +5
Recently, solid-state mechanical resonators have become a platform for demonstrating non-classical behavior of systems involving a truly macroscopic number of particles. Here, we p…
Bounding entanglement dimensionality from the covariance matrix
Shuheng Liu, Matteo Fadel, Qiongyi He +2
High-dimensional entanglement has been identified as an important resource in quantum information processing, and also as a main obstacle for simulating quantum systems. Its certif…
Characterizing Multipartite Non-Gaussian Entanglement for Three-Mode Spontaneous Parametric Down-Conversion Process
Mingsheng Tian, Yu Xiang, Feng-Xiao Sun +2
Very recently, strongly non-Gaussian states have been observed via a direct three-mode spontaneous parametric down-conversion in a superconducting cavity [Phys. Rev. X 10, 011011 (…
Multiparameter quantum metrology and mode entanglement with spatially split nonclassical spin states
Matteo Fadel, Benjamin Yadin, Yuping Mao +2
We identify the multiparameter sensitivity of split nonclassical spin states, such as spin-squeezed and Dicke states spatially distributed into several addressable modes. Analytica…
Homodyne detection of non-Gaussian quantum steering
Carlos E. Lopetegui, Manuel Gessner, Matteo Fadel +2
Quantum correlations are at the core of current developments in quantum technologies. Certification protocols of entanglement and steering, suitable for continuous-variable non-Gau…
