Replacing Quantum Feedback with Open-Loop Control and Quantum Filtering
Joshua Combes, Howard M. Wiseman, A. J. Scott
Feedback control protocols can stabilize and enhance the operation of quantum devices, however, unavoidable delays in the feedback loop adversely affect their performance. We intro…
Teleportation fidelity as a probe of sub-Planck phase-space structure
A. J. Scott, Carlton M. Caves
We investigate the connection between sub-Planck structure in the Wigner function and the output fidelity of continuous-variable teleportation protocols. When the teleporting parti…
Generic local distinguishability and completely entangled subspaces
Jonathan Walgate, A. J. Scott
A subspace of a multipartite Hilbert space is completely entangled if it contains no product states. Such subspaces can be large with a known maximum size, S, approaching the full…
Tight informationally complete quantum measurements
A. J. Scott
We introduce a class of informationally complete positive-operator-valued measures which are, in analogy with a tight frame, "as close as possible" to orthonormal bases for the spa…
