Abstract

AN APPARATUS FOR FLIPPING THE POLARIZATION STATE OF AN OPTICAL PULSE BETWEEN A TRANSMITTER (2) AND A RECEIVER (4) IN A QUANTUM KEY DISTRIBUTION SYSTEM COMPRISING: A PASSIVE NON FLIPPING COMPONENT (340) THAT PRESERVES THE POLARIZATION STATE OF SAID OPTICAL PULSE; A PASSIVE FLIPPING COMPONENT (350) THAT ROTATES THE POLARIZATION STATE OF SAID OPTICAL PULSE ORTHOGONALLY; AND AN ACTIVE OPTICAL SWITCH (320) THAT RECEIVES SAID OPTICAL PULSE AND SENDS SAID OPTICAL PULSE TO EITHER THE SAID PASSIVE NON FLIPPING COMPONENT (340) OR THE SAID PASSIVE FLIPPING COMPONENT (350) WHEREBY THE SAID OPTICAL PULSE UPON ENTERING SAID ACTIVE OPTICAL SWITCH (320) IS DIRECTED EITHER TOWARDS THE PASSIVE NON FLIPPING COMPONENT (340) WHERE ITS POLARIZATION STATE IS PRESERVED OR TOWARDS THE PASSIVE FLIPPING COMPONENT (350) WHERE ITS POLARIZATION STATE IS ROTATED ORTHOGONALLY.
