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.…

Geometric Approach to Digital Quantum Information
Chad Rigetti, Remy Mosseri, Michel Devoret
We present geometric methods for uniformly discretizing the continuous N-qubit Hilbert space. When considered as the vertices of a geometrical figure, the resulting states form the…
