Arbitrary quantum control of qubits in the presence of universal noise

Author: Green, TJ ; Sastrawan, J ; Uys, H ; Biercuk, MJ Date: Sep 2013 We address the problem of deriving analytic expressions for calculating universal decoherence-induced errors in qubits undergoing arbitrary, unitary, time-dependent quantum control protocols. We show that the fidelity of a control operation ... Read more
Maintaining quantum coherence in the presence of noise through state monitoring

Author: Konrad, T ; Uys, H Date: Jan 2012 Unsharp measurements allow the estimation and tracking of quantum wave functions in real time with minimal disruption of the dynamics. Here we demonstrate that high-fidelity state monitoring, and hence quantum control, is possible, even in ... Read more
Quantum control through measurement feedback

Author: Uys, Hermann ; Bassa, H ; Du Toit, P ; Ghosh, S ; Konrad, T Date: Jun 2018 Measurement combined with feedback that aims to restore a presumed premeasurement quantum state will yield this state after a few measurement-feedback cycles even if the actual state of the system initially had no resemblance to the presumed ...
