The dynamics of a double-dot charge qubit embedded in a suspended phonon cavity

Pure dephasing of double-quantum-dot charge qubits in freestanding slabs

“…In fact, electron-phonon interaction is one of the major sources of decoherence. [11][12][13][14][15][16][17] The phonon effects on the performance of charge qubit are also evaluated in symmetrical DQD system. 18 Generally, there are two important mechanisms constituting decoherence: relaxation and pure dephasing.…”
