Broadband parametric amplification for multiplexed SiMOS quantum dot signals
Victor Elhomsy, Luca Planat, David J. Niegemann +14
Spins in semiconductor quantum dots hold great promise as building blocks of quantum processors. Trapping them in SiMOS transistor-like devices eases future industrial scale fabric…

Complete readout of two-electron spin states in a double quantum dot
Martin Nurizzo, Baptiste Jadot, Pierre-André Mortemousque +9
We propose and demonstrate complete spin state readout of a two-electron system in a double quantum dot probed by an electrometer. The protocol is based on repetitive single shot m…

Parity and singlet-triplet high fidelity readout in a silicon double quantum dot at 0.5 K
David J. Niegemann, Victor El-Homsy, Baptiste Jadot +14
We demonstrate singlet-triplet readout and parity readout allowing to distinguish T0 and the polarized triplet states. We achieve high fidelity spin readout with an average fidelit…
