Can we generate highly nonclassical states of light without relying on post-selection? Our newest paper shows that the answer is yes. We propose a deterministic protocol for the generation of multi-photon-added coherent states using photon blockade in a driven Kerr resonator. Instead of waiting for rare heralding events, the desired quantum state emerges directly from the system dynamics, achieving remarkably high fidelities under realistic experimental conditions. While this may sound like a highly specialized problem, it addresses a broader challenge in quantum science: how to reliably engineer complex quantum states on demand. Engineering quantum states of light is one of the foundational capabilities required for the development of emerging quantum technologies. From quantum sensing and communications to future quantum information platforms, advancing our ability to prepare, manipulate, and control nonclassical states is an essential step toward making these technologies a reality. Congratulations to our team PhD(c) Mariano Uria y Pablo Solano (Udec) and to our collaborator Ricardo Gutiérrez-Jáuregui (UNAM) on this exciting result.
