Giacomo Marocco
Welcome! I’m a postdoctoral researcher in the Physics Division at Berkeley Lab. I am working to understand the quantum mechanics of the devices that we are building to discover new fundamental physics. This often involves a fun blend of quantum measurement theory, quantum optics, and particle theory. I am doing this in the Quantum Measurement group, run by Dan Carney.
Research
Many quantum experiments are being built in the effort to discover new physics. I like to make sure that these quantum sensors work well by modeling them and coming up with new architectures or sensing protocols.
Previously, I spent a lot of time doing particle physics, searching for new particles in old experiments, and proposing new experiments one could envisage doing.
Quantum sensing
I’m currently most interested in optical and superconducting systems.
Teams at Berkeley Lab and Yale are developing a levitated nanoparticle platform to search for sterile neutrinos, called the Quantum Invisible Particle Sensor (QuIPS). I have worked on increasing the sensitivity of this optomechanical system through quantum protocols. One can use squeezed light to do this, although I have also shown that one can directly squeeze the motional state of the particle, which is the first practical procedure to increase sensitivity along all three directions.
