Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
Fully Directional Quantum-limited Phase-Preserving Amplifier
Gangqiang Liu, Andrew Lingenfelter, Vidul R. Joshi +4
We present a way to achieve fully directional, quantum-limited phase-preserving amplification in a four-port, four-mode superconducting Josephson circuit by utilizing interference…
Magnetic field-resilient quantum-limited parametric amplifier
Mingrui Xu, Risheng Cheng, Yufeng Wu +2
Superconducting parametric amplifiers are crucial components in microwave quantum circuits for enabling quantum-limited signal readout. The best-performing such amplifiers are ofte…
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…
Multiparametric Amplification and Qubit Measurement with a Kerr-free Josephson Ring Modulator
T. -C. Chien, O. Lanes, C. Liu +6
Josephson-junction based parametric amplifiers have become a ubiquitous component in superconducting quantum machines. Although parametric amplifiers regularly achieve near-quantum…
