Micro-cavity integration with monolithic linear ion trap
Abstract: Micro optical cavities can be used to collect photons emitted from the ions more efficiently, or to achieve strong coupling between photons and ions. In this talk, I will discuss a fundamen...

Reliable quantum cloning at the Heisenberg limit
Abstract: No process in nature can perfectly copy an arbitrary quantum state. But is it possible to engineer processes that replicate quantum states with vanishingly small error? We devised a probabi...

Critical thermalization of a disordered dipolar spin system in diamond
Abstract: Statistical mechanics underlies our understanding of macroscopic quantum systems. It is based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium states, fo...
