Three-wave mixing traveling-wave parametric amplifier with periodic variation of the circuit parameters
Anita Fadavi Roudsari, Daryoush Shiri, Hampus Renberg Nilsson +8
We report the implementation of a near-quantum-limited, traveling-wave parametric amplifier that uses three-wave mixing (3WM). To favor amplification by 3WM, we use the superconduc…
A high gain travelling-wave parametric amplifier based on three-wave mixing
Hampus Renberg Nilsson, Anita Fadavi Roudsari, Daryoush Shiri +2
We extend the theory for a Josephson junction travelling wave parametric amplifier (TWPA) operating in the three-wave mixing regime and we propose a scheme for achieving high gain.…
Qubit-compatible substrates with superconducting through-silicon vias
K. Grigoras, N. Yurttagül, J. -P. Kaikkonen +21
We fabricate and characterize superconducting through-silicon vias and electrodes suitable for superconducting quantum processors. We measure internal quality factors of a million…
