Carbon nanotube composites for thermal management
Single-wall carbon nanotubes (SWNTs) were used to augment the thermal transport properties of industrial epoxy. Samples loaded with 1 wt % unpurified SWNT material showed a 70% increase in thermalExpand
Electrical Transport in Single-Wall Carbon Nanotubes
We review recent progress in the measurement and understanding of the electricalproperties of individual metal and semiconducting single-wall carbon nanotubes. Thefundamental scattering mechanismsExpand
Engineered two-dimensional Ising interactions in a trapped-ion quantum simulator with hundreds of spins
A spin-dependent optical dipole force can produce an antiferromagnetic interaction, and this demonstration, coupled with the high spin count, excellent quantum control and low technical complexity of the Penning trap, brings within reach the simulation of otherwise computationally intractable problems in quantum magnetism.

Dynamical decoupling sequence construction as a filter-design problem
Over the past decade we have seen an explosion of demonstrations of quantum coherence in atomic, optical and condensed matter systems. These developments have placed a new emphasis on the productionExpand
Thermal properties of carbon nanotubes and nanotube-based materials
Abstract.The thermal properties of carbon nanotubes are directly related to their unique structure and small size. Because of these properties, nanotubes may prove to be an ideal material for theExpand
Optimized dynamical decoupling in a model quantum memory
The extension of a treatment to predict qubit decoherence under realistic conditions is extended, yielding strong agreement between experimental data and theory for arbitrary pulse sequences incorporating nonidealized control pulses, demonstrating the robustness of qubit memory error suppression through dynamical decoupling techniques across a variety of qubits.

Qiskit Backend Specifications for OpenQASM and OpenPulse Experiments
A specification for a common interface to backends and a standarized data structure (Qobj --- quantum object) for sending experiments to those backends via Qiskit and OpenPulse, a language for specifying pulse level control of a general quantum device independent of the specific hardware implementation are provided.

Reducing sequencing complexity in dynamical quantum error suppression by Walsh modulation
We study dynamical error suppression from the perspective of reducing sequencing complexity, with an eye toward facilitating the development of efficient semiautonomous quantum-coherent systems. ToExpand
Near-ground-state transport of trapped-ion qubits through a multidimensional array
We have demonstrated transport of {sup 9}Be{sup +}ions through a two-dimensional Paul-trap array that incorporates an X junction, while maintaining the ions near the motional ground state of theExpand
