Traveling-Wave Parametric Amplifier with Passive Reverse Isolation
C. S. Kow, M. T. Bell
Traveling-wave parametric amplifiers (TWPAs) have attracted much attention for their broadband amplification and near-quantum-limited noise performance. TWPAs are non-reciprocal by…

Self phase-matched broadband amplification with a left-handed Josephson transmission line
C. Kow, V. Podolskiy, A. Kamal
Josephson Traveling Wave Parametric Amplifiers (J-TWPAs) are promising platforms for realizing broadband quantum-limited amplification of microwave signals. However, substantial ga…

Strong coupling diagnostics for multi-mode open systems
C. Kow, Z. Xiao, A. Metelmann +1
We present a new method to diagnose strong coupling in multi-mode open systems. Our method presents a non-trivial extension of exceptional point (EP) analysis employed for such sys…
