Generation of universal linear optics by any beam splitter
Adam Bouland,Scott Aaronson +1 more
TLDR
In this paper, a beam splitter that acts nontrivially on two modes can be used to generate a dense set of all unitary transformations on single photons in three or more modes, thereby making tunable beam splitters nonessential in principle for universal optical transformations.Abstract:

Microwave photonics with superconducting quantum circuits
TL;DR: In the past 20 years, impressive progress has been made both experimentally and theoretically in superconducting quantum circuits, which provide a platform for manipulating microwave photons as mentioned in this paper, and many higher-order effects, unusual and less familiar in traditional cavity quantum electrodynamics with natural atoms, have been experimentally observed.

Classical simulation of photonic linear optics with lost particles
Michał Oszmaniec,Daniel J. Brod +1 more
TL;DR: In this paper, the authors explore the possibility of efficient classical simulation of linear optics experiments under the effect of particle losses and show that it is possible to approximate the output statistics already if the number of photons that are left grows logarithmically with ε, regardless of the geometry of the network.

TL;DR: It is shown that the scheme is universal even when the block's transfer matrices are chosen at random, making it virtually insensitive to errors, and the placement of the variable elements can be arbitrary, so that the Scheme is not bound to specific topologies.
