The quantum adiabatic search with decoherence in the instantaneous energy eigenbasis
Johan Åberg, David Kult, Erik Sjöqvist
In Phys. Rev. A {\bf 71}, 060312(R) (2005) the robustness of the local adiabatic quantum search to decoherence in the instantaneous eigenbasis of the search Hamiltonian was examine…
Gluing of completely positive maps
Johan Åberg
Gluings of completely positive maps (CPMs) are defined and investigated. As a brief description of this concept consider a pair of `evolution machines', each with the ability to ev…
Subspace local quantum channels
Johan Åberg
A special class of quantum channels, named subspace local (SL), are defined and investigated. The proposed definition of subspace locality of quantum channels is an attempt to answ…
Subspace preserving completely positive maps
Johan Åberg
A class of quantum channels and completely positive maps (CPMs) are introduced and investigated. These, which we call subspace preserving (SP) CPMs has, in the case of trace preser…
