Spin-coherent quantum designs
Marcin Rudziński, Aaron Z. Goldberg, Andrei B. Klimov +2
Coherent states bridge the gap between quantum and classical physics, but their overcomplete and nonorthogonal nature makes it difficult to identify the minimal discrete set needed…
Metrological Advantages in Seeded and Lossy Nonlinear Interferometers
Jasper Kranias, Guillaume Thekkadath, Khabat Heshami +1
The quantum Fisher information (QFI) bounds the sensitivity of a quantum measurement, heralding the conditions for quantum advantages when compared with classical strategies. Here,…
Multiphoton interference in a single-spatial-mode quantum walk
Kate L. Fenwick, Jonathan Baker, Guillaume S. Thekkadath +6
Multiphoton interference is crucial to many photonic quantum technologies. In particular, interference forms the basis of optical quantum information processing platforms and can l…
Quadrature Coherence Scale of Linear Combinations of Gaussian Functions in Phase Space
Anaelle Hertz, Aaron Z. Goldberg, Khabat Heshami
The quadrature coherence scale (QCS) is a recently introduced measure that was shown to be an efficient witness of nonclassicality. It takes a simple form for pure and Gaussian sta…
