Transport through coupled quantum dots
Tobias Brandes
Abstract
Abstract A brief survey of theoretical activities on electronic transport in coupled charge qubits is given. Some subtleties of the double quantum dot model (infinite bias, infinitely strong Coulomb blockade) are pointed out, and the motivation behind using ac‐field, noise and entanglement as a probe for testing transport in a simple setting is discussed.
