Dephasing in a crystal-phase defined double quantum dot charge qubit strongly coupled to a high-impedance resonator
Antti Ranni, Subhomoy Haldar, Harald Havir +8
Dephasing of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence. To this e…
