The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides...
Polarization modes for strong-field gravitational waves
Polarization modes strong-field gravitational waves
2010/12/20
Strong-field gravitational plane waves are often represented in either the Rosen or Brinkmann forms. These forms are related by a coordinate transformation, so they should describe essentially the sam...

One fundamental requirement for quantum computation is to perform universal manipulations
of quantum bits at rates much faster than the qubit’s rate of decoherence. Recently,
fast gate operations ha...
