Abstract: Control qubits impact different applications ranging from quantum sensing, quantum engineering and cooling to weak measurements. In this talk, Raul Coto reviews some of these applications and its implementation with color centers in diamond. Special attention will be given to fast coherent control of nuclear spins, preparation and cooling of mechanical oscillators, dynamical phase transitions and quantum sensing. Finally, prospects for machine learning, neural networks, quantum machine learning and quantum computing will be given.

Short Bio: Coto finished his PhD in 2015 at the Pontificia Universidad Católica de Chile, where he studied the propagation and distribution of quantum correlations in cavity QED arrays. After that, he started a postdoctoral fellowship at the same university, studying quantum sensing and coherent control with a Nitrogen-Vacancy
center. In 2017 Coto joined Universidad Mayor as assistant professor at the center for quantum optics and quantum information. In 2019 he created a PhD program in physics and the DAiTA Lab research center, where he still works. Coto is mainly interested in two quantum systems, namely cavity QED arrays and color centers in diamond.
For these systems Coto studied quantum control, sensing and phase transitions. Recently, he has been working on quantum computing, machine learning, quantum machine learning and neural networks.
