Electric g Tensor Control and Spin Echo of a Hole-Spin Qubit in a Quantum Dot Molecule
Robert Roloff, Thomas Eissfeller, Peter Vogl +1
The feasibility of high-fidelity single-qubit operations of a hole spin in a quantum dot molecule by electric g tensor control is demonstrated. Apart from a constant external magne…
Optimal Control for Open Quantum Systems: Qubits and Quantum Gates
Robert Roloff, Markus Wenin, Walter Pötz
This article provides a review of recent developments in the formulation and execution of optimal control strategies for the dynamics of quantum systems. A brief introduction to th…
Time-optimal performance of Josephson charge qubits: A process tomography approach
Robert Roloff, Walter Pötz
A process tomography based optimization scheme for open quantum systems is used to determine the performance limits of Josephson charge qubits within current experimental means. Th…
Bell-state preparation for electron spins in a semiconductor double quantum dot
Robert Roloff, Walter Pötz
A robust scheme for state preparation and state trapping for the spins of two electrons in a semiconductor double quantum dot is presented. The system is modeled by two spins coupl…
