Abstract : We perform a quantum simulation of the Ising model with a transverse field using a collection of three trapped atomic ion spins. By adiabatically manipulating the Hamiltonian, we directly probe the ground state for a wide range of fields and form of the Ising couplings, leading to a phase diagram of magnetic order in this microscopic system. The technique is scalable to much larger numbers of trapped ion spins, where phase transitions approaching the thermodynamic limit can be…

Transport as a sensitive indicator of quantum criticality

In the limit of weak-coupling between spins and bosons, the quantum-optical master equation is applied to calculate the energy transmitted from source to drain reservoirs and it is found that the critical behaviour of the ground state is mapped to critical behaviours of the current--even in configurations with infinite thermal bias.

Digital quantum simulation of the statistical mechanics of a frustrated magnet.

A 'digital' quantum simulation of thermal states is reported; a three-spin frustrated magnet was simulated using a nuclear magnetic resonance quantum information processor, and the phase diagram of the system is explored at any simulated temperature and external field.

Topological Characterization of Extended Quantum Ising Models.

The winding number can serve as a topological quantum number of the quantum phases in the extended quantum Ising model, which sheds some light upon the relation between quantum phase transition and the geometrical order parameter characterizing the phase diagram.

The first experimental simulation of quantum tunneling through potential barriers, a widespread phenomenon of a unique quantum nature, via NMR techniques is reported, which has clearly demonstrated the possibility to observe and study profound physical phenomena within even the reach of small quantum computers.

Here, a quantum simulation of frustrated Ising spins in a system of three trapped atomic ions, whose interactions are precisely controlled using optical forces is realized, finding a link between frustration and ground-state entanglement.

Entanglement and tunable spin-spin couplings between trapped ions using multiple transverse modes.

T tunable spin-spin couplings between trapped atomic ions are demonstrated, mediated by laser forces on multiple transverse collective modes of motion, which provides a new class of interactions relevant to quantum computing and simulation with large collections of ions in a single crystal.

Ground states of a frustrated quantum spin chain with long-range interactions.

It is shown that the continuous (infinite-order) Dimerization transition develops into a first-order transition between a long-range ordered antiferromagnetic state and a state with coexisting dimerization and critical spin correlations at wave number k=pi/2.
