Substrate surface engineering for high-quality silicon/aluminum superconducting resonators
C. T. Earnest, J. H. Béjanin, T. G. McConkey +4
Quantum bits (qubits) with long coherence times are an important element for the implementation of medium- and large-scale quantum computers. In the case of superconducting planar…
Multiplexed dispersive readout of superconducting phase qubits
Yu Chen, D. Sank, P. O'Malley +13
We introduce a frequency-multiplexed readout scheme for superconducting phase qubits. Using a quantum circuit with four phase qubits, we couple each qubit to a separate lumped-elem…
Excitation of superconducting qubits from hot non-equilibrium quasiparticles
J. Wenner, Yi Yin, Erik Lucero +15
Superconducting qubits probe environmental defects such as non-equilibrium quasiparticles, an important source of decoherence. We show that "hot" non-equilibrium quasiparticles, wi…
Controlled catch and release of microwave photon states
Yi Yin, Yu Chen, Daniel Sank +13
The quantum behavior of superconducting qubits coupled to resonators is very similar to that of atoms in optical cavities [1, 2], in which the resonant cavity confines photons and…
Dynamic quantum Kerr effect in circuit quantum electrodynamics
Yi Yin, H. Wang, M. Mariantoni +14
A superconducting qubit coupled to a microwave resonator provides a controllable system that enables fundamental studies of light-matter interactions. In the dispersive regime, pho…
Phase qubits fabricated with trilayer junctions
M. Weides, R. C. Bialczak, M. Lenander +11
We have developed a novel Josephson junction geometry with minimal volume of lossy isolation dielectric, being suitable for higher quality trilayer junctions implemented in qubits.…
Energy decay and frequency shift of a superconducting qubit from non-equilibrium quasiparticles
M. Lenander, H. Wang, Radoslaw C. Bialczak +12
Quasiparticles are an important decoherence mechanism in superconducting qubits, and can be described with a complex admittance that is a generalization of the Mattis-Bardeen theor…
A Superconducting 180° Hybrid Ring Coupler for circuit Quantum Electrodynamics
E. Hoffmann, F. Deppe, T. Niemczyk +11
Superconducting circuit quantum electrodynamics experiments with propagating microwaves require devices acting as beam splitters. Using niobium thin films on silicon and sapphire s…
Generation of Three-Qubit Entangled States using Superconducting Phase Qubits
M. Neeley, R. C. Bialczak, M. Lenander +11
Entanglement is one of the key resources required for quantum computation, so experimentally creating and measuring entangled states is of crucial importance in the various physica…
Two-resonator circuit QED: Dissipative Theory
Georg M. Reuther, David Zueco, Frank Deppe +9
We present a theoretical treatment for the dissipative two-resonator circuit quantum electrodynamics setup referred to as quantum switch. There, switchable coupling between two sup…
Two-photon probe of the Jaynes-Cummings model and symmetry breaking in circuit QED
Frank Deppe, Matteo Mariantoni, E. P. Menzel +9
Superconducting qubits behave as artificial two-level atoms and are used to investigate fundamental quantum phenomena. In this context, the study of multi-photon excitations occupi…
