Practical Limits to Single-Mode Vacuum Squeezing with a SNAIL Parametric Amplifier
Theodore Shaw, Debsuvra Mukhopadhyay, Zhuoqun Hao +4
We characterize single-mode vacuum squeezing generated by a SNAIL Parametric Amplifier (SPA) operated under conditions representative of practical sensing and qubit-readout experim…

Experimental signatures of a beam-splitter interaction between a Kerr-cat and transmon qubit
Josiah Cochran, Haley M. Cole, Hebah Goderya +5
Quantum error correction (QEC) requires ancilla qubits to extract error syndromes from data qubits which store quantum information. However, ancilla errors can propagate back to th…

Wireless Josephson parametric amplifier above 20 GHz
Z. Hao, J. Cochran, Y. -C. Chang +2
Operating superconducting qubits at elevated temperatures offers increased cooling power and thus system scalability, but requires suppression of thermal photons to preserve cohere…
