Description
Trapped ions are an ideal platform for the quantum simulation of various models of interacting quantum matter. In this talk, I will give an overview of quantum simulations with trapped ions, where coherent time evolution competes with incoherent operations, such as the measurement and reset of the quantum state of only a part of the system. Such ‘mid-circuit’ measurement and reset operations can lead to the creation of non-trivial quantum phases of matter that cannot be obtained through coherent evolution alone. I will describe our group's efforts in building the toolbox to realize such quantum simulations, including the demonstration of in situ measurement of a trapped ion qubit without accidentally measuring its neighbors. Our work involves exquisite control of laser radiation targeted at individual ions through programmable holography, as well as using the ion itself as a sensor for aberrations. Measurement-driven quantum phases are generally intractable on classical computers, underscoring the importance of using quantum simulators to explore such phases.
