Dephasing of coupled qubit system during gate operations due to background charge fluctuations
Toshifumi Itakura, Yasuhiro Tokura
A quantum computer that can be constructed based on a superconducting nanocircuits has previously been proposed. We examine the effect of background charge fluctuations on a couple…
