Excitation Spectrum of a Bose-Einstein Condensate
TL;DR: The excitation spectrum displays a linear phonon regime, as well as a parabolic single-particle regime, and agrees well with the Bogoliubov spectrum in the local density approximation, even close to the long-wavelength limit of the region of applicability.

Process tomography of quantum memory in a Josephson-phase qubit coupled to a two-level state
Matthew Neeley,Markus Ansmann,Radoslaw C. Bialczak,Max Hofheinz,Nadav Katz,Erik Lucero,A. D. O’Connell,Hulin Wang,Andrew Cleland,John M. Martinis +9 more
TL;DR: In this paper, it was shown that the interaction between the circuit and defects is accurately controlled, and that the imperfections might be useful, serving as memory elements for a quantum information processor.
Microwave dielectric loss at single photon energies and millikelvin temperatures
Aaron D. O'Connell,Markus Ansmann,Radoslaw C. Bialczak,Max Hofheinz,Nadav Katz,Erik Lucero,Christopher McKenney,Matthew Neeley,Haohua Wang,Eva M. Weig,Andrew Cleland,John M. Martinis +11 more
TL;DR: In this article, the authors present the loss tangents of some common amorphous and crystalline dielectrics, measured at low temperatures (T < 100mK) with near single-photon excitation energies, using both coplanar waveguide and lumped LC resonators.

Molecular Hydrogen Formation on Astrophysically Relevant Surfaces
TL;DR: In this paper, the authors analyzed the formation of molecular hydrogen on astrophysically relevant surfaces under conditions close to those encountered in the interstellar medium using rate equations and fitted the parameters of the rate equation model to temperature-programmed desorption curves obtained in the laboratory.
State Tomography of Capacitively Shunted Phase Qubits with High Fidelity
Matthias Steffen,Markus Ansmann,Robert McDermott,Nadav Katz,Radoslaw C. Bialczak,Erik Lucero,Matthew Neeley,Eva M. Weig,Andrew Cleland,John M. Martinis +9 more
TL;DR: A new design concept is introduced in which the capacitive element is explicitly separate from the Josephson tunnel junction for improved qubit performance and the number of two-level systems that couple to the qubit is reduced and the measurement fidelity improves to 90%.
