In this talk, I will give an overview of some of the ongoing efforts to build a photonic quantum computer. I will start by discussing the boson sampling problem and how it lead to some of the first claims of demonstrations of quantum computational speedups. A boson sampler is a non-universal quantum computer that is able to interfere multiple photons over many optical modes and detect the photons are at the output. I will discuss what kind of interesting physics of bosonic particles can be observed in such devices and mention different strategies to check if the device is working correctly in a regime where it cannot be simulated by classical computers. I will also present some recent research about the interference of partially distinguishable bosons, such as photons with some differences in their internal degrees of freedom (polarization, frequency, etc.), and explain how the transition between bosonic statistics and classical statistics can be observed in these systems.
