  • Abstract
    A simple design for Bob in two-way quantum key distribution schemes that employs only passive linear optical components to perform the necessary switching operations is presented. It is shown that, for some specific protocols and/or practical qubit implementations, the losses in Bob´s station can be made negligible, hence increasing the maximum distance for secret key generation.
