Adiabatic information transport in the presence of decoherence
I. Kamleitner, J. Cresser, J. Twamley
We study adiabatic population transfer between discrete positions. Being closely related to STIRAP in optical systems, this transport is coherent and robust against variations of e…
Globally controlled fault tolerant quantum computation
J. Fitzsimons, J. Twamley
We describe a method to execute globally controlled quantum information processing which admits a fault tolerant quantum error correction scheme. Our scheme nominally uses three sp…
Quantum switching networks for perfect qubit routing
C. Facer, J. Twamley, J. D. Cresser
We develop the work of Christandl et al. [M. Christandl, N. Datta, T. C. Dorlas, A. Ekert, A. Kay, and A. J. Landahl, Phys. Rev. A 71, 032312 (2005)], to show how a d-hypercube hom…
The Quantum Mellin transform
J. Twamley, G. J. Milburn
We uncover a new type of unitary operation for quantum mechanics on the half-line which yields a transformation to ``Hyperbolic phase space''. We show that this new unitary change…
Unambiguous discrimination among oracle operators
Anthony Chefles, Akira Kitagawa, Masahiro Takeoka +2
We address the problem of unambiguous discrimination among oracle operators. The general theory of unambiguous discrimination among unitary operators is extended with this applicat…
