    "abstract": "In previous quantum key distribution (QKD) protocols, information is encoded\non either the discrete-variable of single-photon signal or continuous-variables\nof multi-photon signal. Here, we propose a new QKD protocol by encoding\ninformation on continuous-variables of a single photon. In this protocol, Alice\nrandomly encodes her information on either the central frequency of a\nnarrow-band single photon pulse or the time-delay of a broadband single photon\npulse, while Bob randomly chooses to do either frequency measurement or time\nmeasurement. The security of this protocol rests on the energy-time uncertainty\nrelation, which prevents Eve from simultaneously determining both frequency and\ntime information with arbitrarily high resolution. In practice, this scheme may\nbe more robust against various channel noises, such as polarization and phase\nfluctuations.",
