Quantum mechanical approach to decoherence and relaxation generated by fluctuating environment
Quantum mechanical approach to decoherence and relaxation generated by fluctuating environment
We consider an electrostatic qubit, interacting with fluctuating charge of a single-electron transistor (SET) in the framework of an exactly solvable model. The SET plays role of an environment affecting the qubits' parameters in a controllable way. We derive the rate equations describing the dynamics of the entire system for …
