Antonio Ferrer-Sánchez

Physicist working on machine learning for physics

I build physics-informed neural networks: models trained against the equations a system obeys, not only against data. I use them to solve and control physical systems, from relativistic fluids and black-hole oscillations to quantum control and sensing.

I am a Quantum Algorithm Engineer at Kipu Quantum and a PhD student at the Universitat de València, in the Intelligent Data Analysis Laboratory.
