Abstract: Present day quantum technologies aim at building quantum computers and networks that outperform their classical counterparts. From a physical perspective, these technologies need to be systems whose parameters are modified in real time, so that a programable sequence of operations is performed to deliver different quantum applications. Then, it is only natural to consider parametric oscillators as a primitive for these devices. In this seminar, we will discuss the basics of parametric oscillators in superconducting circuits and their applications to two promising topics: Firstly, the generation of multipartite entanglement thanks to the parametric amplification of vacuum in microwave one-dimensional cavities. Additionally, we will introduce protocols for the detection of said entanglement, which lead to connections in open questions in quantum information theory. Secondly, we will present superconducting circuits designed for the analog simulation of relativistic phenomena such as the Unruh and dynamical Casimir effects.
