The Interspersed Spin Boson Lattice Model
A. Kurcz, J. J. Garcia-Ripoll, A. Bermudez
We describe a family of lattice models that support a new class of quantum magnetism characterized by correlated spin and bosonic ordering [Phys. Rev. Lett. 112, 180405 (2014)]. We…
Noise Studies of Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We present a study of the performance of the trapped-ion driven geometric phase gates introduced in [New J. Phys. 15, 083001 (2013)] when realized in a stimulated Raman transition.…
Lieb-Robinson bounds for spin-boson lattice models and trapped ions
J. Juenemann, A. Cadarso, D. Perez-Garcia +2
We derive a Lieb-Robinson bound for the propagation of spin correlations in a model of spins interacting through a bosonic lattice field, which satisfies itself a Lieb-Robinson bou…
Controlling and measuring quantum transport of heat in trapped-ion crystals
A. Bermudez, M. Bruderer, M. B. Plenio
Measuring heat flow through nanoscale systems poses formidable practical difficulties as there is no `ampere meter' for heat. We propose to overcome this problem by realizing heat…
Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We describe a hybrid laser-microwave scheme to implement two-qubit geometric phase gates in crystals of trapped ions. The proposed gates can attain errors below the fault-tolerance…
Frustrated Quantum Spin Models with Cold Coulomb Crystals
A. Bermudez, J. Almeida, F. Schmidt-Kaler +2
We exploit the geometry of a zig-zag cold-ion crystal in a linear trap to propose the quantum simulation of a paradigmatic model of long-ranged magnetic frustration. Such a quantum…
