New lower bounds on the non-zero capacity of Pauli Channels
Jesse Fern, K. Birgitta Whaley
We study encodings that give the best known thresholds for the non-zero capacity of quantum channels, i.e., the upper bound for correctable noise, using an entropic approach to cal…
Adaptive homodyne phase discrimination and qubit measurement
Mohan Sarovar, K. Birgitta Whaley
Fast and accurate measurement is a highly desirable, if not vital, feature of quantum computing architectures. In this work we investigate the usefulness of adaptive measurements i…
Multi-particle decoherence free subspaces in extended systems
Raisa I. Karasik, Karl-Peter Marzlin, Barry C. Sanders +1
We develop a method to determine spatial configurations to realize decoherence-free subspaces for spatially extended multi-particle systems. We have assumed normal reservoir behavi…
Criteria for dynamically stable decoherence-free subspaces and incoherently generated coherences
Raisa I. Karasik, Karl-Peter Marzlin, Barry C. Sanders +1
We present a detailed analysis of decoherence free subspaces and develop a rigorous theory that provides necessary and sufficient conditions for dynamically stable decoherence free…
