Journal ArticleDOI
An architecture for integrating planar and 3D cQED devices
Christopher Axline,Matthew Reagor,Reinier Heeres,Philip Reinhold,Chen Wang,K. Shain,Wolfgang Pfaff,Yiwen Chu,Luigi Frunzio,Robert Schoelkopf +9 more
TL;DR: In this paper, a coaxial transmission line device architecture with coherence similar to traditional 3D cQED systems is introduced, and the authors integrate a resonator-qubit system in this architecture with a seamless 3D cavity, and separately pattern a qubit, readout resonator, Purcell filter and high-Q stripline resonator on a single chip.
Journal ArticleDOI
Measuring the decoherence of a quantronium qubit with the cavity bifurcation amplifier
M. Metcalfe,E. Boaknin,Vladimir E. Manucharyan,R. Vijay,Irfan Siddiqi,Chad Rigetti,Luigi Frunzio,Robert Schoelkopf,Michel Devoret +8 more
TL;DR: In this paper, the cavity bifurcation amplifier (CBA) is applied to the readout of the quantronium qubit, which is based on a simple coplanar waveguide imposing a predetermined frequency and whose other rf characteristics such as the quality factor are easily controlled and optimized.
Journal ArticleDOI
Decoherence of superconducting qubits caused by quasiparticle tunneling
TL;DR: In this paper, a theory of the pure dephasing rate caused by quasiparticles tunneling through a Josephson junction and of inhomogeneous broadening due to changes in the occupations of Andreev states in the junction was developed.
Journal ArticleDOI
Noise performance of the radio-frequency single-electron transistor
Leif Roschier,Pertti Hakonen,K. Bladh,Per Delsing,Konrad Lehnert,Lafe Spietz,Robert Schoelkopf +6 more
TL;DR: In this paper, a radio-frequency single-electron-transistor (RF-SET) circuit with an HEMT amplifier and an impedance transformer is analyzed, where the authors consider how power is transferred between different components of the circuit, model noise components, and analyze the operating conditions.
Journal ArticleDOI
To catch and reverse a quantum jump mid-flight
Zlatko Minev,Zlatko Minev,Shantanu Mundhada,Shyam Shankar,Philip Reinhold,R. Gutiérrez-Jáuregui,Robert Schoelkopf,Mazyar Mirrahimi,Mazyar Mirrahimi,H. J. Carmichael,Michel Devoret +10 more
TL;DR: In this article, the jump from the ground to an excited state of a superconducting artificial three-level atom can be tracked as it follows a predictable "flight," by monitoring the population of an auxiliary energy level coupled to the ground state.
