Local-oscillator-agnostic squeezing detection
Suchitra Krishnaswamy, Dhrithi Maria, Laura Ares +3
We address the problem of measuring nonclassicality in continuous-variable bosonic systems without having access to a known reference signal. To this end, we construct broader clas…
Quasiprobabilities from incomplete and overcomplete measurements
Jan Sperling, Laura Ares, Elizabeth Agudelo
We discuss the (re-)construction of quasiprobability representations from generic measurements, including noisy ones. Based on the measurement under study, quasiprobabilities and t…
Unified boson sampling
Luca Bianchi, Carlo Marconi, Laura Ares +2
Boson sampling is a key candidate for demonstrating quantum advantage, and has already yielded significant advances in quantum simulation, machine learning, and graph theory. In th…
Multiphoton, multimode state classification for nonlinear optical circuits
Denis A. Kopylov, Christian Offen, Laura Ares +5
We introduce a new classification of multimode states with a fixed number of photons. This classification is based on the factorizability of homogeneous multivariate polynomials an…
Universal Topology of Exceptional Points in Nonlinear Non-Hermitian Systems
N. H. Kwong, Jan Wingenbach, Laura Ares +4
Exceptional points (EPs) are non-Hermitian degeneracies where eigenvalues and eigenvectors coalesce, giving rise to unusual physical effects across scientific disciplines. The conc…
Restricted Monte Carlo wave function method and Lindblad equation for identifying entangling open-quantum-system dynamics
Laura Ares, Julien Pinske, Benjamin Hinrichs +2
We develop an extension of the Monte Carlo wave function approach that unambiguously identifies dynamical entanglement in general composite, open systems. Our algorithm performs ta…
