Josephson Array Mode Parametric Amplifier
V. V. Sivak, S. Shankar, G. Liu +2
We introduce a novel near-quantum-limited amplifier with a large tunable bandwidth and high dynamic range - the Josephson Array Mode Parametric Amplifier (JAMPA). The signal and id…
Quantum error correction of a qubit encoded in grid states of an oscillator
P. Campagne-Ibarcq, A. Eickbusch, S. Touzard +10
Quantum bits are more robust to noise when they are encoded non-locally. In such an encoding, errors affecting the underlying physical system can then be detected and corrected bef…
Kerr-free three-wave mixing in superconducting quantum circuits
V. V. Sivak, N. E. Frattini, V. R. Joshi +3
Quantum-limited Josephson parametric amplifiers are crucial components in circuit QED readout chains. The dynamic range of state-of-the-art parametric amplifiers is limited by sign…
