===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>.
