Electrostatic control of quasiparticle poisoning in a hybrid semiconductor-superconductor island
H. Q. Nguyen, D. Sabonis, D. Razmadze +8
The performance of superconducting devices is often degraded by the uncontrolled appearance and disappearance of quasiparticles, a process known as poisoning. We demonstrate electr…
Local and non-local two-electron tunneling processes in a Cooper pair splitter
Antti Ranni, Elsa T. Mannila, Axel Eriksson +3
We measure the tunneling rates and coupling coefficients for local Andreev, non-local Andreev and elastic cotunneling processes. The non-local Andreev process, giving rise to Coope…
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…
