Abstracts:
We review our experiment on quantum source and channel
codings, the most fundamental operations in quantum info-communications.
For both codings, entangling letter states is essential. Our model is
based on the polarization-location coding, and a quasi-single photon
linear optics implementation to entangle the polarization and location
degrees of freedom. Using single-photon events in a subset of possible
cases, we simulate quantum coding-decoding operations for nonorthogonal
states under the quasi-pure state condition. In the quantum channel
coding, we double the spatial bandwidth (number of optical paths), and
demonstrate the information more than double can be transmitted. In the
quantum source coding, we halve the spatial bandwidth to compress the
data and decompress the original data with the high fidelity approaching
the theoretical limit.
