Title: Advances in Quantum Simulation and Sensing Using Two Dimensional Ion Crystals
Abstract: Two-dimensional crystals of ions generated by the use of a Penning trap offer the possibility of scalable quantum information processing with samples of as many as 500 ions. Up to date, nevertheless, most of the protocols used in the Penning trap typically operate in a far-detuned regime where the phonons of the crystal are used only to mediate interactions between the internal states in the ions (spins). Consequently, the generated spin–spin interactions are slow compared to the original spin-phonon coupling, making any generated entanglement susceptible to decoherence. In this talk I will discuss schemes that resonantly couple internal and motional degrees of freedom and fully leverage the available spin-phonon coupling. In particular, I will describe how these schemes can be used to create metrologically useful states for electric field sensing or phase estimation or entangled states for quantum teleportation which enjoy the beneficial short timescales associated with the resonant interactions. This work suggests new capabilities offered by trapped ions for the preparation of many-body states with tailored correlations for quantum-enhanced metrology, which can access physics beyond the standard-model, and for information processing tasks.
