Phonon Decoherence of a Double Quantum Dot Charge Qubit
Serguei Vorojtsov, Eduardo R. Mucciolo, Harold U. Baranger
We study decoherence of a quantum dot charge qubit due to coupling to piezoelectric acoustic phonons in the Born-Markov approximation. After including appropriate form factors, we…
Spin Qubits in Multi-Electron Quantum Dots
Serguei Vorojtsov, Eduardo R. Mucciolo, Harold U. Baranger
We study the effect of mesoscopic fluctuations on the magnitude of errors that can occur in exchange operations on quantum dot spin-qubits. Mid-size double quantum dots, with an od…
Coulomb blockade peak spacing fluctuations in deformable quantum dots: a further test to Random Matrix Theory
Raul O. Vallejos, Caio H. Lewenkopf, Eduardo R. Mucciolo
We propose a mechanism to explain the fluctuations of the ground state energy in quantum dots in the Coulomb blockade regime. Employing the random matrix theory we show that shape…
