    "abstract": "A new quantum communication scheme is introduced which is the quantum\nrealization of the classical Kish-Sethuraman (KS) cipher. First the message is\nbounced back with additional encryption by the Receiver and the original\nencryption is removed and the message is resent by the Sender. The mechanical\nanalogy of this operation is using two padlocks; one by the Sender and one by\nthe Receiver. We show that the rotation of the polarization is an operator\nwhich satisfies the conditions required for the KS encryption operators\nprovided single photons are communicated. The new method is not only simple but\nhas several advantages. The Evasdropper extracts zero information even if she\nexecutes a quantum measurement on the state. The communication can be done by\ntwo publicly agreed orthogonal states. Therefore, there is no inherent\ndetection noise. No classical channel and no entangled states are required for\nthe communication.",
