Introducing the Transmon: a new superconducting qubit from optimizing the Cooper Pair Box
Jens Koch,Terri M. Yu,Jay M. Gambetta,Andrew Houck,David Schuster,Johannes Majer,Alexandre Blais,Michel Devoret,Steven Girvin,Robert Schoelkopf +9 more
TL;DR: In this paper, a transmon was proposed to operate in a regime of significantly increased ratio of Josephson energy and charging energy, where the transmon benefits from the fact that its charge dispersion decreases exponentially with $E_J/E_C$ while its loss in anharmonicity is described by weak power law.

Violating Bell's inequality with an artificial atom and a cat state in a cavity
Brian Vlastakis,Andrei Petrenko,Nissim Ofek,Luayn Sun,Zaki Leghtas,K. Sliwa,Yehan Liu,Michael Hatridge,Jacob Blumoff,Luigi Frunzio,Mazyar Mirrahimi,Liang Jiang,Michel Devoret,Robert Schoelkopf +13 more
TL;DR: In this paper, the authors demonstrate and quantify entanglement between an artificial atom and a cat state in a cavity, which they call a ''Bell-cat' state'' and investigate the influence of decoherence by continuously varying the size of created Bell-cat states and characterize the entangled system by joint Wigner tomography.

Fabrication of tunnel junctions for direct detector arrays with single-electron transistor readout using electron-beam lithography
Thomas R. Stevenson,Wen-Ting Hsieh,M. J. Li,K. W. Rhee,Robert Schoelkopf,C.M. Stahle,J.D. Teufel +6 more
TL;DR: In this article, the fabrication of small aluminum tunnel junctions for applications in astronomy is described, where measurement and modification of the sensitivity ratio in the resist bilayer was used to greatly improve the reliability of forming devices with uniform, sub-micron size, low-leakage junctions.
Journal ArticleDOI
High-On-Off-Ratio Beam-Splitter Interaction for Gates on Bosonically Encoded Qubits
Benjamin Chapman,Sophia H. Xue,Yaxing Zhang,James Teoh,Jacob C. Curtis,Takahiro Tsunoda,Alec Eickbusch,Alexander P. Read,A. Koottandavida,Shantanu Mundhada,Luigi Frunzio,Michel Devoret,Steven Girvin,Robert Schoelkopf +13 more
TL;DR: In this paper , a 3-wave mixing coupling element was used to engineer a programmable beamsplitter interaction between two bosonic modes separated by more than an octave in frequency, without introducing major additional sources of decoherence.
