A closed-system approach to quantum retrodiction in open systems

A.J. Scroggie, J. Jeffers

Research output: Contribution to journalArticlepeer-review


Ban (Int. J. Theor. Phys. 46:184, 2007) has shown how retrodictive open systems evolution may be treated as unitary using non-equilibrium thermo field dynamics. Here we describe the application of another technique with the same purpose, Fano diagonalisation.
