A near-quantum-limited Josephson traveling-wave parametric amplifier.
Detecting single-photon level signals—carriers of both classical and quantum information—is particularly challenging for low-energy microwave frequency excitations. Here we introduce a superconducting amplifier based on a Josephson junction transmission line. Unlike current standing-wave parametric amplifiers, this traveling wave architecture robustly achieves high gain over a bandwidth of seve...

متن کاملQuantum wideband traveling-wave analysis of a degenerate parametric amplifier
We develop a wideband traveling-wave formalism for analyzing quantum mechanically a degenerate parametric amplifier. The formalism is based on spatial differential equations-spatial Langevin equations-that propagate temporal Fourier components of the field operators through the nonlinear medium. In addition to the parametric nonlinearity, the Langevin equations include absorption and associated...
متن کاملGyro-Traveling Wave Amplifier
The theory, design and experimental results of a wideband 140 GHz, 1 kW pulsed gyro-traveling wave amplifier are presented. The gyro-TWA operates in the HE(0,6) mode of an overmoded quasi-optical waveguide using a gyrating electron beam. The electromagnetic theory, interaction theory, design processes and experimental procedures are described in detail. At 37.7 kV and 2.7 A beam current, the ex...
متن کاملTRAVELING WAVE PARAMETRIC AMPLIFIER WITH JOSEPHSON JUNCTIONS USING MINIMAL RESONATOR PHASE MATCHING (SUPPLEMENTARY INFORMATION) Coupled Mode Equations
where ∆k = ki+ks−2kp is the phase mismatch calculated from weak-signal dispersion of the transmission line. The term on the right hand side of the pump equation represents the selfphase modulation due to the AC pump current interacting with itself. Analogous cross-phase modulation processes are represented by the rst term on the right hand side of the signal and idler equations; the other term ...
