My research focuses on engineering and exploiting quantum states in driven-dissipative systems.
A dissipative system is a quantum system coupled to an external environment, which can be understood as an infinite set of degrees of freedom. In these open quantum systems, losses and driving coexist: for instance, if the environment is in vacuum, it will act as a channel for losses, which must be compensated by some sort of external driving if one wants the system to be in a state different from a boring vacuum state.
The combination of losses and driving eventually yields a non-equilibrium stationary state. The dissipative character of these systems is a source of decoherence that tends to wash away any of its quantum properties, such as coherence or entanglement. However, one can still engineer stationary states with quantum properties by exploiting elements such as the type excitation, the structure of the environment, and the non-linearities induced by light-matter interaction.
The study of driven-dissipative systems is of tremendous interest for the development of quantum technologies, since any useful quantum device must be connected to the outside world (us) to be of any use! With proper engineering, the states dissipated to the environment can even carry the quantum features developed in the system, allowing us to exploit them (e.g., the emission of quantum light) or give valuable information about what is going on inside!
Below you can find more details on my research lines, all of which revolve in some way or another around these ideas.
