Editing Quantum Oblivious Transfer (section)

===Preparation phase===

# The receiver tells the sender the quantum efficiency <math>q</math> and the dark count rate <math>d</math> of his detectors.
# If satisfactory, the sender tells the receiver the value of <math>\mu</math>, <math>a</math>, <math>\epsilon</math> and <math>N</math>.
# Then they agree on a linear binary error-correcting code capable of correcting with very high probability N-bit words transmitted with expected error rate <math>\epsilon</math>.
# Finally, both the parties perform a test run.
## The sender sends pulses of intensity <math>\mu</math> in a prearranged sequence of polarizations.
## The receiver reads each pulse in the correct basis
## He then verifies if he can detect the pulses with probability greater than <math>a</math> and error rate less than <math>\epsilon</math>.
