• Abstract: Quantum rotors promise unique advantages for quantum sensing, quantum simulation, and quantum information processing. At present, a variety of systems ranging from nanoparticles to single molecules and trapped ions have demonstrated detection and control of rotational motion in and near the quantum regime. For future applications of quantum rotors, understanding their dynamics in the presence of ambient environments and decoherence will be critical. While other model quantum systems such as the harmonic oscillator have seen extensive experimental study of their decoherence dynamics, such experiments remain an open task for the rigid rotor. We present measurements of fundamental scaling relationships for decoherence of a quantum planar rotor realized with two trapped ions, and find excellent agreement with recent theoretical work.

• Quantum criticality in chains of planar rotors with dipolar interactions [0.0]
  By exploring the ground state from weakly to strongly interacting rotors, we find the occurrence of a quantum phase transition between a disordered and a dipole-ordered quantum state. We show that the nature of the ordered state changes from ferroelectric to antiferroelectric when the relative orientation of the rotor planes varies. The observed quantum phase transitions are characterized by critical exponents and central charges which reveal different universality classes ranging from that of the (1+1)D Ising model to the 2D classical XY model.

  A quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins. These interactions can be accounted for by a long-wavelength relativistic theory, where the phonons are described by a coarse-grained Klein-Gordon field. We show that thermal effects, which can be controlled by laser cooling, can unveil this flow through the appearance of thermal masses in interacting QFTs.

  coherent dynamics and control of spin qubits are essential requirements for quantum technology.
