US Patent 7449672 - Quantum information conversion system
http://www.freepatentsonline.com/7449672.html
This patent from HP teaches a more efficient quantum information processing system involving conversion of the physical representation of the quantum state (e.g. photon number, polarization, time bin, or orbital angular momentum) at different stages of the processing. Claim 1 reads:
1. A system comprising:
a channel for an input photon state that uses a first physical representation for quantum information; and
a photo-interactive system that interacts with the input photon state to generate an output photon state using a second physical representation for the quantum information, wherein:
the first physical representation uses a first property to encode the quantum information; and
the second physical representation uses a second property to encode the quantum information, the second property differing from the first property.
