Description
Arrays of trapped ions offer precise control over both internal quantum states and collective vibrational motion. Here, we demonstrate the manipulation of vibrational modes in ion arrays to drive the 1D linear–2D zigzag quantum structural phase transition. This system provides an intrinsic source of novel entangled states of ion crystal structures, which can be manipulated through trapped ion double-well interferometry. I will discuss how we experimentally control and characterize this transition in a linear Paul trap, using Raman sideband spectroscopy to probe energy levels and motional distributions near the critical point. Finally, I will explore coherence assessment and potential applications in in-situ electric field noise sensing.
