Jeffrey M. Epstein


I am a theoretical physicist broadly interested in quantum information and quantum computation. At present, I work as a Quantum Applications Engineer at Atom Computing in Berkeley, California, where we are building a quantum computer based on trapped neutral atoms. I'm always happy to talk to anyone interested in quantum information!

I received my PhD in physics from UC Berkeley, where I was worked with Professors Kranthi Mandadapu and Birgitta Whaley. Before that, I obtained my masters at Perimeter institute in Waterloo, Ontario and my AB at Harvard College. For more information, please see my CV.
