Tracking an open quantum system using a finite state machine: stability analysis
Raisa I. Karasik, Howard M. Wiseman
A finite-dimensional Markovian open quantum system will undergo quantum jumps between pure states, if we can monitor the bath to which it is coupled with sufficient precision. In g…
Efficient tracking of the state of a qubit
Raisa I. Karasik, Howard M. Wiseman
We study resource requirements for tracking the state of an open qubit subject to continuous observation. This problem is of great importance for quantum control.
How many bits does it take to track an open quantum system?
R. I. Karasik, H. M. Wiseman
A -dimensional Markovian open quantum system will undergo quantum jumps between pure states, if we can monitor the bath to which it is coupled with sufficient precision. In gene…
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…
