Measuring relational information between quantum states, and applications
Michał Oszmaniec, Daniel J. Brod, Ernesto F. Galvão
The geometrical arrangement of a set of quantum states can be completely characterized using relational information only. This information is encoded in the pairwise state overlaps…
Witnesses of coherence and dimension from multiphoton indistinguishability tests
Taira Giordani, Chiara Esposito, Francesco Hoch +5
Quantum coherence marks a deviation from classical physics, and has been studied as a resource for metrology and quantum computation. Finding reliable and effective methods for ass…
Linear-optical dynamics of one-dimensional anyons
Allan D. C. Tosta, Ernesto F. Galvão, Daniel J. Brod
We study the dynamics of bosonic and fermionic anyons defined on a one-dimensional lattice, under the effect of Hamiltonians quadratic in creation and annihilation operators, commo…
Experimental quantification of genuine four-photon indistinguishability
Taira Giordani, Daniel J. Brod, Chiara Esposito +7
Photon indistinguishability plays a fundamental role in information processing, with applications such as linear-optical quantum computation and metrology. It is then necessary to…
Classical simulation of linear optics subject to nonuniform losses
Daniel Jost Brod, Michał Oszmaniec
We present a comprehensive study of the impact of non-uniform, i.e.\ path-dependent, photonic losses on the computational complexity of linear-optical processes. Our main result st…
Regimes of classical simulability for noisy Gaussian boson sampling
Haoyu Qi, Daniel J. Brod, Nicolás Quesada +1
As a promising candidate for exhibiting quantum computational supremacy, Gaussian Boson Sampling (GBS) is designed to exploit the ease of experimental preparation of Gaussian state…
