An RF-Driven Josephson Bifurcation Amplifier for Quantum Measurements
I. Siddiqi, R. Vijay, F. Pierre +5
We have constructed a new type of amplifier whose primary purpose is the readout of superconducting quantum bits. It is based on the transition of an RF-driven Josephson junction b…
Direct Observation of Dynamical Switching between Two Driven Oscillation States of a Josephson Junction
I. Siddiqi, R. Vijay, F. Pierre +8
We performed a novel phase sensitive microwave reflection experiment which directly probes the dynamics of the Josephson plasma resonance in both the linear and non-linear regime.…
Dephasing of Electrons in Mesoscopic Metal Wires
F. Pierre, A. B. Gougam, A. Anthore +3
We have extracted the phase coherence time of electronic quasiparticles from the low field magnetoresistance of weakly disordered wires made of silver, copper and gold. In sa…
Magnetic-field-dependent quasiparticle energy relaxation in mesoscopic wires
A. Anthore, F. Pierre, H. Pothier +1
In order to find out if magnetic impurities can mediate interactions between quasiparticles in metals, we have measured the effect of a magnetic field B on the energy distribution…
