Coulomb Blockade Peak Spacings: Interplay of Spin and Dot-Lead Coupling
Serguei Vorojtsov, Harold U. Baranger
For Coulomb blockade peaks in the linear conductance of a quantum dot, we study the correction to the spacing between the peaks due to dot-lead coupling. This coupling can affect m…
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 Oscillations of Conductance at Finite Energy Level Spacing in a Quantum Dot
Serguei Vorojtsov
We find an analytical expression for the conductance of a single electron transistor in the regime when temperature, level spacing, and charging energy of a grain are all of the sa…
