Exponential improvement in benchmarking multiphoton interference
Rodrigo M. Sanz, Emilio Annoni, Stephen C. Wein +4
Several photonic quantum technologies rely on the ability to generate multiple indistinguishable photons. Benchmarking the level of indistinguishability of these photons is essenti…

Invariants in Linear Optics
Sébastien Draux, Simon Perdrix, Emmanuel Jeandel +1
Linear optics (LO) prohibits certain transformations. In this paper, we study the conditions for a computation to be possible in LO. We find that there are finitely many polynomial…

New designs of linear optical interferometers with minimal depth and component count
Timothée Goubault de Brugière, Rawad Mezher, Sebastian Currie +1
We adapt an algorithm for CNOT circuits synthesis based on the Bruhat decomposition to the design of linear optical circuits with Mach-Zehnder interferometers (MZI). The synthesis…
