Coherent quantum state storage and transfer between two phase qubits via a resonant cavity
Mika A. Sillanpaa, Jae I. Park, Raymond W. Simmonds
A network of quantum-mechanical systems showing long lived phase coherence of its quantum states could be used for processing quantum information. As with classical information pro…
A Josephson Junction Microscope for Low-frequency Fluctuators
L. Tian, R. W. Simmonds
The high-Q harmonic oscillator mode of a Josephson junction can be used as a novel probe of spurious two-level systems (TLSs) inside the amorphous oxide tunnel barriers of the junc…
Decoherence in Josephson Qubits from Dielectric Loss
John M. Martinis, K. B. Cooper, R. McDermott +8
Dielectric loss from two-level states is shown to be a dominant decoherence source in superconducting quantum bits. Depending on the qubit design, dielectric loss from insulating m…
Observation of quantum oscillations between a Josephson phase qubit and a microscopic resonator using fast readout
K. B. Cooper, Matthias Steffen, R. McDermott +5
We have detected coherent quantum oscillations between Josephson phase qubits and microscopic critical-current fluctuators by implementing a new state readout technique that is an…
Decoherence in Josephson Qubits from Junction Resonances
R. W. Simmonds, K. M. Lang, D. A. Hite +2
Although Josephson junction qubits show great promise for quantum computing, the origin of dominant decoherence mechanisms remains unknown. We report Rabi oscillations for an impro…
